There is nothing, absolutely fucking nothing, that the on-topic area benefits from by having A&H's continued existence. It is tolerated. I tolerate it because 1) the on-topic users still deserve a place to discuss politics, and 2) I don't know what happens if I delete it. I know what happens if it stays up, and sort of like an invasive kudzu I can take a flamethrower and singe off the most retarded faggots every few months. I don't know what happens if I try to torch the whole thing all at once.
People like AgendaPoster represent the opposite of what I want to see, which is on-topic posters sheltering in place on the forum during droughts of content, forging friendships that keeps the community healthy even when things are slow or times are hard. AgendaPoster is an off-topic user who intrudes into the on-topic posters, picks fights, alienates users, and damages the ecosystem I am solely responsible for managing. Ultimately, it is my responsibility to decide who I tolerate and don't tolerate. Allowing people to pick fights and damage the parts of the site that actually generate content that improves the forum is a personal shortcoming and a personal failure which I have to remedy myself if I am unhappy with it.
