Humans are designed to eat meat along with other things, while I respect a persons decision to veer away from it, they have no right to try and interfere with my life. I couldn't care less about their opinion of what i'm eating. Just like an overweight person who is eating cake shouldn't have someone jump down their throat because of the calorie content, get over it. I'm not ignorant to the fact i'm eating animals, I simply choose to do it, vegans often act like they have some sort of revelation to display, it's like religious cultist.
Fact of the matter is, if you're at my table eating a vegan meal, I won't comment on it outside of asking if you enjoy it, I respect most decisions people make until they attempt to interfere with mine. You won't enlighten me or change my mind on that subject.
