I've noticed this

Similar with the people who don't give a fuck about women's sports except for an excuse to marginalize trans people

They've been conditioned to respond to certain key phrases with certain responses.
So the trigger goes trans women -> care -> women's sports but you don't get women's sports -> care.
Or veganism -> care -> nutrition but not nutrition -> care.
Our brains are weird things, they have to develop links between ideas in both directions or else they stay one-way. It takes real work and discipline to develop critical thinking practices, and even then you have to keep working at it to minimise this kind of cognitive dissonance, and you'll never get rid of it entirely.
Of course it helps if you're not miseducated by authoritarian schooling practices and conservative media.

....how do vegans know what meaty humans taste like?

You could look at veganism as the practice of avoiding products from animals that can't consent, which doesn't necessarily take cannibalism off the table.
- Rammstein in the distance
- Well, that would make some very interesting "consenting" cheese.
  Love me some queso de mamacita
Oral was what I thought the implication was. Lithi-cum ion batteries lol
- Isn’t semen an animal product?
Well, when a mommy vegan and a daddy vegan love each other very much...

Fuck batteries, with keto I taste like fingernail polish remover!

I only eat polar bear liver in order to make my flesh and fluids outright toxic.
- You just have more Vitamin Alpha than those cucks can handle.

I've read that vegans average fewer nutrient deficiencies than omnivores. People should be worrying more about getting enough whole-food fiber than they are about protein.

Yes and no because when vegans get nutrient deficient it hits them hard. Lack of fibre is completely benign compared to deficiencies in essential micronutrients -- fibre is not essential. You can have a maize and MSG diet if that also includes about two eggs a week your body is not going to be well off but it's going to cope instead of collapse.
And lots of prospective vegans are hit by those deficiencies, and then drop out, at least out of strict veganism. Nothing like a gal's period stopping to scare them off. Which, conversely, means that if vegans want to actually grow their numbers they should stop being all blase about nutrition. It definitely is possible to get enough iron, even as a gal, from a vegan diet but yes you gotta eat your lentils. There's alternatives but how in the everloving does it happen that people turn vegan and don't eat enough, of all things, lentils. I probably eat enough lentils and I'm not even vegan.
- I'm a vegan. Lentils aren't a regular part of my diet. I'm willing to bet that they aren't in a lot of people's diets. I live in the US, and you kind of have to seek out lentils here. They aren't a rare and exotic food or anything like that, but which foods can you buy, ready-made, that contain lentils? Soup is about the only one I can think of.
- Reject lentils, embrace broccoli 🥦
  Actually btw. Broccoli and spinach have much higher iron levels.
- I wonder what kind of diet vegans are following that get deficiencies. I've been vegan for years (started because I had high cholesterol levels), and the only thing I've worried about is B12, which I get from enriched soy products or nutritional yeast. I try to just buy what's in season locally, then find vegan recipes or recipes that can easily be substituted to make vegan. I don't even eat much of the trendy "superfoods" like quinoa, kale, lentils, etc. More like collard/sweet potato/beet greens, chickpeas, pinto beans, root veggies, etc. I dunno where I get my iron from; probably greens. I also use veg or olive oil pretty liberally, especially in recipes that traditionally include beef or pork.
I'm not Vegan, but I like trying to find Vegan meals I really enjoy, or close enough. One close enough is a bulgur bowl dish, using meat replacement and shawarma seasoning, tomatoes, cucumbers, sometimes chickpeas, sometimes grilled onions, and then the nonvegan parts: goat cheese and feta. Goat cheese is mixed with a little olive oil, garlic, and lemon juice to make it a sauce. There's no meat but ther is cheese, and it's a nice fiberous dish that helps reduce my meat intake anyway.

There are many subcultures around food. It's not like the world is split between vegans and junk food addicts.

The Cheeto and McDonalds eating crowd may have crappy nutrition but they're an extreme. The other extreme is meal-preppers. They know exactly how much chicken, rice and broccoli they're eating.

There are huge communities of people who are very health conscious. Some of them focus their consciousness on science, some of them on other methods. Some of those people are vegans. Some aren't.

Nice to see a sane take.
Thing is anyone health conscious already knows that you can have good nutrition with a vegan diet. Anyone generalizing veganism as having bad nutrition without looking at the specifics of what someone is eating has no idea what they're talking about and probably don't have good nutrition themselves if they're that uninformed

Tf they think vegan people taste like rainbows and sunsets?

Having had vegan girlfriends and a wife who was vegan for a bit I can attest it makes a difference. Maybe not rainbows but they tasted much sweeter and more mild than average.
- Yeah wife and i cut way back on meat, body odor in general is less.. gamey? Smokey? Something.
  I really like it, I'm easily overwhelmed by strong smells and I can usually wear unscented deodorant now. I used to funk right through it immediately.
Vegans have more fruits and vegetables inside them so have a higher level of fermentation apparently. Everyone does to a certain extent, but I've found that occasionally it can lead to more gas (eat more grains)

I care for literally nothing about veganism; weirdly though it's starting to pop up everywhere I look this week.

You should care. Its important
