Do I need a good argument for you to respect my opinion?

But what if my perspective differs?
Argumentation cannot account for that.
Argumentation requires a shared perspective and shared axioms.
- If a worldview is devoid of reason and no argument will dissuade the person, all useful dialog is impossible.

If it's a subjective matter then no. Like if you thought Blade Runner sucked I might disagree with your opinion but respect that it's a matter of taste and so I won't recommend you see the sequel.

If you're just using "opinion" as a shield for something objective then yes I will. And I will laugh at you for thinking the sky is falling is a matter of opinion.

Depending on what you mean by respect and opinion, yes. If you're discussing an opinion then someone is probably going to expect you to explain why, that's a logical point to cover in any such discussion. Even if it's subjective. If it's an opinion on something objective, then there's an actual burden of "proof" and possible consequences, and the stakes rise accordingly.

There aren't many reasons to "properly" respect an opinion that is irrational (not just subjective), factually wrong ("interpretation" only goes so far), dishonest, or anything like that. I'm skeptical of endorsing any opinion until I know why it is what it is.

Sort of. I respect your right to have an opinion, but I'll respect the opinion a lot more if backed by facts and data.

It depends on how harmful that opinion is. You prefer vanilla ice cream because you like the mild flavor - cool, difference of opinion. You prefer there were no same-sex marriages because your religion is against it - no, that affects other people’s lives so if you want me to respect that opinion you would have to have a good argument.

If it's a totally subjective opinion, no. You can like food I don't, or even have kinks I don't.

If it's even slightly fact-based, kind of yes, unless you keep it entirely to yourself. I don't have to agree with it to respect it, though, if you have any reasonable kind of argument.

Like someone else said, in practice nobody actually cares what I respect.

People that spend energy on arguing their right to have opinions rather than defending the opinion are deeply uninteresting and often stupid people that I don't not respect in any capacity.

I do agree those people you speak about are uninteresting and mostly stupid.
But we should respect stupid people, their ideas aren't always worth respecting, but as people they themselves deserve considering.
And I praise anyone that has the patience to teach morons to be better people despite their own lack of judgment.
- I described a behaviour and two qualities. I said that people with the behaviour often have these two qualities. I then said I dont respect people with that behaviour.
  There are a lot if people that are stupid but still fun and interesting people. They have skills that I don't have and perspectives that I don't have. They have found ways to interact with the world that works with their shortcomings. I respect them.
  Some stupid people decide to hide their stupidity by spending a lot of time arguing that they shouldn't have to elaborate on their opinion and we should treat all opinions the same without scrutiny. They dont grow, they dont learn, they make their own shortcomings other peoples problem. I dont respect them.
Yeah those guys are the worst.
Hahahahaha yeah, no. You dont need to be smart to be able to talk someone down. Not everyone who is smart wants to fight others every step of the way.
Making statements that degrade others like this shows a deep lack of understanding and empathy.
that the sky is blue for your doesnt mean its blue for everyone. Sure you can debate people, with consent though.
Have a good one.

Yes

What if they simply see things differently?
Chocolate is better than vanilla. Argument? Of course not.
Argument requires shared assumptions. If the assumptions are not shared then you can't argue.
And then what's left? Respect for the individual?

I would say yes. The only time you don’t is when I already agree with you, but that’s because I (hopefully) already know the good argument.

I don’t believe in “common sense”, that’s just the biases someone already has. Some of them correct, some of them not, all unchecked therefore all invalid as a basis for anything.

If we could dispose of respect for the individual, then we could replace democracy with science. That would be efficient.
- Science doesn’t have values, and policy needs values. Science can tell you the best way to achieve your values, but if your values don’t align with the values of the majority of people, then you’re going to use science to make people unhappy.
  It sounds like you just want to impose your values onto other people, which is precisely what democracy was invented to protect people against.

Depends on what it is about. We meet and you say :

You're vegan. Good.
You use Linux. Good.
You're on the Fediverse. Good.
You love bicycles. Good.

Now we meet again and you talk about privacy and then ask for my WhatsApp number (which is non existing) to continue that conversation later -> The heat is on! 🔥

So it depends on the threat level. That's prudent.

OP asked this less than 24 hours before they went mask-off as a Fascist.

Yes, you do need a good argument. And no, Forced sterilization and eugenics isn't a good argument or even a conversation worth dignifying.

Edit: OP has deleted their post after an avalanche of downvotes and dissenting comments. I have some screenshots, although I expect OP to delete this post too.

OP letting the mask slip:

Extremely concerning shit

Extraordinary claims require extraordinary evidence.

If your opinion is that kittens are cute, I'm on board. If your opinion is that everyone over 30 should be sterilized unless they are in a top 10 percent earning category, you're going to have to work for respect for that, and better have a damn convincing argument.

So, yes, unless.
Does the plain fact that somebody said it carry any weight?
- If you're a vetted expert in the field in question. Yes, I'll give your opinion weight. I e. The millions of scientists and doctors talking about vaccines.
  If you're a chad who watched a YouTube video, no I'll dismiss you as the idiot you are.

If you want to persuade me to think the way you do, yes.

What if I want the right to vote?
- Your opinion doesn’t need to be respectable for you to have the right to vote.

Depends on how consequential it is. If it's about Taylor Swift it doesn't matter, feel however you want, but if it's about how society should be run than yeah you kinda do

The you are agreement with others here. It depends on the threat level.

Who cares if internet jerks respect your opinion?

It doesn't matter until you get some power and use it to make your ideas prevail
That is a very good question.

This is a spread from yes to no where "yee" applies to hypothetical things that are fully objective and "no" to hypothetical things that are fully subjective

You’re entitled to your opinion and I’m entitled to eviscerate your opinion if it is my opinion that it’s shit.

Though I try to debate ideas with logic and evidence.

Is simply being a living breathing person sufficient to garner your respect?
- My default is to respect all people. It’s on you to lose my respect.

Can you give an example of what you mean by someone respecting your opinion and someone not respecting it?

As many others have said in this thread, it comes down to how you define "respect" and "opinion". Based on some of your responses, I think you are using a broad definition of "opinion", though some more clarification might be useful there. If you're worried about partisanship adding bias, try offering equivalent opinions from different directions as examples, eg "I think Trump should be president" and "I think Biden should be president".

What many?

No, but you need a good argument if you want me to support or act on your opinion.

How does authority figure in?
I don't understand his reasoning but he's got a good reputation. Or cites such.
- No

I respect facts and objective evidence. Opinion is immaterial.

Otherwise, there is no point to it.

Unfortunately there are many subjects where all the facts aren't known, therefore opinions must be discussed to advance the understanding and ultimately help to establish future facts. Also, one person's believed facts may be a misunderstanding, for example, hence why discussions and arguments may happen.
As such, there is (nearly) always a point to it!
