Oh, dude, trust me - there's plenty about the fanbase to dislike, no doubt about it. Fortunately, most of the fans I have a problem with are all concentrated on a couple sites. I don't know anyone IRL who even knows what Touhou is, so I can't speak to the frustration of some asshat in my school suddenly liking it. I have reacted the way you have about people I don't like suddenly liking the same bands I do, though, and for like, a split second it'll make me question my own tastes. So I do get it.
