I hate most vegetarians and vegans.
BUT I don't hate vegetarianism and veganism in itself. There are many good reasons to be vegetarian or vegan.
Most of them act like they are so much better than everyone else and so enlightened. They are mostly just miserable and weak whiny things that make things awkward for everyone.
p.s. I used to be vegan so I can understand both sides.
I mostly hate when people stop eating meat as a weight loss thing and then preach about it. LAME.
When I was vegan, my cousin put a pig's tail on my dinner plate, grr.
I guess it's not the social phenomenon that you hate but stuck-up behaviour in general. That's pretty common.
