Most people's values and beliefs are all wrapped up with their sense of self, so if those beliefs get attacked, they feel like they're being attacked.
Avoiding this is very tricky and counter-intuitive, but there are techniques. Look up "street epistemology" if you'd like to know more. There's a guy on YouTube who goes to college campuses and has discussions with passersby regarding their beliefs. Basically, it's asking people "What do you believe?" and "Why do you believe that?" Like I said, though, it's tricky and takes a lot of practice, and it's really easy to fall back into old patterns again.
Drugs are only a tool. Drugs aren't going to solve your problems in the same way that a hammer isn't going to build a house. It can help, though. And sometimes you smash your thumb or drop the hammer on your foot.
Just wait. The only reason why Lemmy is more polite is because it's smaller. I think that attitude comes with the territory, unfortunately. If you want to have a less toxic community, the first thing you need to do is get rid of the downvote button. Downvotes are inherently toxic. Lemmy is actually worse than reddit in this regard, because you can actually see the ratio of upvotes to downvotes. So, even if your comment has a high score, you can still feel shitty knowing that X number of people downvoted it.
I'm not saying you should or you shouldn't, but...There have been studies that show that psilocybin mushrooms are effective in treating some forms of trauma, such as PTSD.
All of the (illegal) drugs I ever used made my life better in some way. Whenever somebody tells me that they've never used drugs, I just feel sorry for them, because they've missed out on some great experiences. Of course, there are a few people with unusual brains who should avoid anything psychoactive, but I think the vast majority of people would benefit from it.
I've used it for several years now, and I could never go back. It makes me shudder to think of trying to type out words by tapping on individual letters again. Swiping is so much faster.
I'm not transgender, so you probably should ask them.
What I do know is that this is a major issue for them, to the point where some of them develop bladder issues from avoiding the restroom out of fear of being bullied. When people tell me that something is causing them to suffer, I tend to believe them, unless there's some compelling evidence otherwise.
When I was in college, I knew a transman. One day, I walked into the men's restroom as he was walking out, and one of the other men in the restroom turned to his friend and said, "What's she doing in here?" (Meaning the transman.) Now imagine if you had to deal with the possibility of being bullied that way (or worse!) every time you wanted to use the restroom.
I don't think they should be punished unless they're being a pest.
How would you even enforce that? Are you going to have a bouncer at the door checking to see which genitals somebody has before they can enter the restroom?
I hate to tell you this, but this isn't only a trait of narcissists. This is something that most people do. It's a lot worse with narcissists, though.
