Militant meat eaters are just as annoying as cliché vegans but there seem to be more of the former.
I eat meat from time to time, so definitely not even vegetarian, but I've absolutely run into more offended meat eaters than vegans IRL, but meat at dinner is a big part of my home country's culture.
I remember my sisters' boyfriend fuming, thinking we were trolling him by not having meat at a family dinner. The meat eating mind cannot comprehend.
