For example, c/food is the best general population food forum I've ever seen for my particular needs. A lot of the non-vegan parts of the site is not just tolerant but considerate to vegans. That's frigging unheard of. I don't know what the big deal with shit posters is, but that is hardly the only or defining feature of the culture.
I feel like if you wade into a community you're not a member of and don't understand looking for shit posts, a lot of things are going to look like shit posts.
It's aggressively bad.
