Didn't realise it wasn't allowed on the Ledge ... oops. Is this discussion legit then? Hope I haven't started something anarchic ...
The real person thing is a bit strange alright. Generally it doesn't bother me, but when it comes to slash I think it's crossing the line. I would write fiction about the Mac but mine is more based on them, their songs and so on, not actually featuring them as named characters in their situation.
But slash fanfics involving real people is generally something I feel ought to be steered WELL clear of.
