I think that most RPF people have great sympathy for your squick, and indeed, many may have had the same problem at one time. I have at least one woman on my friends list that has said that she won't so much as watch interviews of bandom people, because if she did, they'd become real people and she'd never be able to write them ever again.

It took me months of full (fandom-)time RPF to get over the occasional squick relapse. Even now, years later, breaking the fourth wall can make me cringe. And I absolutely can't read anything with Grant Morrison in it (though I'm fine with Korse, the character he plays in My Chemical Romance videos). Why? No clue. Apparently my brain feels differently about comic books writers than it does musicians.
