They do in my experience. I’ve never once criticized someone else for eating meat, but I get made fun of a lot for looking for vegetarian/vegan options.
If you just order food without going all “am actually vegan” just to let everyone know and people still make fun of you… then those people are assholes. No one should be judged on their own choices.
Unfortunately, it’s super common. When it comes to my family, they stopped rubbing my face in it once I stood up for myself, which is nice. I had to publicly call out my brother for behaving towards me the way he imagines vegans do before he fully stopped. I have friends who I enjoy the company of, I play board games and tabletop RPGs with them. If I’m round at their place and they’re cooking, sometimes they go into a tirade about how being a vegan is terrible and I have to politely ask them to stop because I’m there to enjoy their company, not defend my eating practices.
It’s thankfully gotten less common, but I honestly think that the whole “angry vegan” stereotype caused them to get on the offensive immediately, expecting a big verbal showdown. I think it’s also this perception of “you think you’re better than me, huh?”.
Now that people know what to expect, sometimes they have questions about why not dairy, or why not eggs. I’m happy to answer those questions, but I’ve never gone into the topic of my own accord.
They are just assholes. It’s not that difficult to make vegan food, they just don’t want to go out of their way to make some for you. I have bunch of vegan and vegetarian friends. Vegans are definitely harder to make food for, but if we are making some food, they better help out if with nothing else with advice or recipes. But I’ve never found it difficult to prepare extra meal or two. It’s just them being lazy.
