A lot of the vegans here are pushing for the end of all meat-eating, so a lot of the non-vegans here (like the guy you responded to about "eating that shit") feel like "nobody should be eating meat anymore" means "you shouldn't eat meat anymore".
Whether "you" is part of "nobody" is a challenging question. I've met plenty of vegans who push for meat bans, and plenty of vegans who otherwise somehow think "since veg tastes good and the only people who eat meat do so feeling guilty, we'll eventually all be vegan anyway". The former are a threat (sorry, they are), and the latter are not worth treating like one.
