I have to agree, in the experience I've had with trolls, they do come across as rather stupid. I got a comment once about one of my long SG-1 slash fics which basically read 'it was good but it would have been much better if it hadn't had Jack and Daniel fall in love, I don't like that pairing anyway, it would have been better if Jack fell in love with Sam.' I felt like pointing out to him/her that if they didn't like the Jack/Daniel pairing, not to read fics with them in it!!!
