Meat-eaters, how does it feel to know there's an entire group of individuals who are better individuals than you are? Meet vegans. They are better than you.
They understand their food better. They understand the basic principles of ethics better. They know how the factory farm system works better than you. They understand the pros and cons of eating meat (including fish and chicken) because with tofu you avoid all sorts of health problems.
They can probably cook, too, since following a vegan diet vastly limits your options (and this really pisses you off, since cooking was one thing you always wanted to do but could never really find any reason not to stuff your face with fast-food.) Oh, and they probably know meat better than you, too, since most advanced PETA vegans these days are ex-carnivores and ex-vegetarians users who managed to love the environment years ago when it was much less "popular."
At this point, a confident individual would admit to himself that he has a lot to learn about PETA and the environment in general, but since you have too much testosterone to do that you eat a hamburger, go to restaurants and keep repeating to yourself "at least I have friends. At least I can go out to dinner with people without being a dick." You're also probably very pleased about being able to eat whatever you want... because KFC or McDonald's have somehow managed to convince you that their greasy cruelty-encumbered food is healthy and taste is the most important thing to consider.
At this point you probably rationalize "well everyone I know is a carnivore, so I'm just going with the status quo!" as if that legitimizes your participation in cow genocide, or that becoming a vegan forces you to lose all taste for meat entirely.
Meet vegans. They're better than you.
This is what I'd say if I was a pretentious asshole vegan.
