Look, veganism is a preference, not a religion. For me, the salient facts are that eating animals and animal products is a) ethically questionable and b) avoidable. But it's just a choice. If I go round someone's house and they've cooked me an otherwise vegan meal but put cheese on top, I'm not going to be a dick about it, I'm going to eat it. Food isn't magic. Maybe this makes me not really vegan, or a "bad vegan" or whatever, but I don't know or care what the rules are. I don't even know any other vegans. It's nobody else's business. I know it's a privilege to be affluent and healthy enough to be able to be selective about what I eat, but I choose to exercise that privilege, just as I choose to exercise other counter-evolutionary privileges like using contraception and not murdering people who annoy me. Could I do more? Could I be a better person? Certainly. Always. But doing this much is so easy that it's a no-brainer, so that's how much I do. Maybe I'll do better tomorrow. I feel kind of shocked and alienated by how aggressively negative some of the posters here are being about that choice.
