Actually you'll know who they are because they're the only ones not eating. Meat eaters are too stupid to understand what a plant is.
Chicken
Fish
Milk butter
Meat based broths
Animal gelatin
Other vegan options include: picking out the meat in vegetables, just this once won't hurt you, or believe me you can't taste it.
Other reasons are I'm casein and lactose intolerant, and I'm allergic to eggs. Plus I have awesome cholesterol. I can pig out if I like and never get fat. My food tastes so good, I couldn't stand it being given a nasty animal taste.
So I'd rather eat my vegan Cliff Bar and drink the wine. Afterwards I can go home, eat my own food and fuck the wife while we paint vegan chocolate sauce swastikas and lick them off eachother.
Yep, life as a vegan is so great, it's our duty to be our brother's keeper.
