I might be oblivious or simply used to it, but I do not find /jp/ to be any worse than any other relatively speedy board. My only great complaints are that every third thread is an excuse to post fanservice, and that the regulars tend to post the same things day after day without variation as some sort of tradition. I think it comes with the territory of having a board dedicated to a bunch of outcasts with an eternal "grass-is-greener" perspective on life; why live your life when its easier to emulate the life of those who you idolize?
At least in my view, what makes a community pathetic is if it serves as a hugbox and a feedback-loop for the members of a community. Someone criticizing you IRL? Complain about it to your comrades and discover how you were in the right all along. Does another group doubt your legitimacy? Turns out they were all Nazis in the making. Much like the anecdote of >>17535 , the farther away a group is from the Overton Window, the more reactionary and defensive they get towards anyone displaying anything resembling a contrary opinion, which also makes them easy to bait if you're into that. Mind you, this has been a thing since the dawn of civilization, but with the transience and equalization that the Internet provides, those with a certain hivemind have to try even harder to preserve their ideology from attacks both outside and inside. It happens with /jp/, subReddits, fetish communities, you name it.
