So what is the percentage of vegans who won’t go out with a meat eater?
Even among the various types of semi-vegetarians (lacto-, pesca-, etc), I'd bet that the percentage is significantly higher than 30%.
The self-proclaimed "moral superiority" of many vegetarians/vegans has always been a huge turn-off for me. (Eat what you want, let me eat what I want, and we'll get along just fine. Preach to me about the evils of my diet and I'll have nothing to do with you.)
More than 30% I damn guarantee.
