I think I'd be more into Utena/Anthy as a pairing if it weren't for the vocal minority of fanatics who will collect and post EVIDENCE that Utena/Anthy is CANON, you have to be BLIND if you don't agree! LOOK at this frame that was cut from the end credits!!! Bonus points if they call people homophobes if they prefer to friend-ship U/A.
In the Slayers fandom, it's not so much the rabidness of the shippers as the consistently bad characterization in the fanfic. I don't know if it's just because Xellos is my favorite and so I notice the OOC-ness more, or if he actually is the most frequent victim, but writers have an unfortunate tendency to write him as either angsty and lovestruck (I haven't read Twilight, but he still tends to remind me of Edward Cullen in those fics) or as Mr. Evil Rapist (which would at least be possible in terms of canon, but still pretty far from his normal personality).
