I never knew Warden/Alistair had an annoying fanbase. Once upon a time I visited the BioWare forums and I read a bit of fic here and there, but...I guess I somehow avoided the worst of it. (I ship my dwarven Warden with Ali. :p)

Arthur/Eames from Inception is the only time I can remember growing to dislike a pairing I shipped.

But usually if I don't like a fandom I'll just stay away from it and that'll be that. *shrugs*
