heheh, haven't these people heard of telepathy, works waaay better than spelling. ^_^
The people who find them arousing probably have seriously cross-wired brains or something. What did you expect I'd say? cross-dressing? toe-fetishes? light S&M?
I don't look for those but I can see why some people would like them and I don't really care what they do as long as they don't make me do them (or watch). Really I'd like to think of myself as open minded (I mean I'll try pretty much anything once with some exceptions mostly what's listed and drugs, I see and know what they do to ever want try them) so as long as there is some sense in it and no one is being hurt I don't care.
now, what do you call sane? (though that's probably harder to define) mostly I think everyone is insane on some level, just depends on how much and in what way.
P.S. this is becoming a really looong chat isn't it? oh well, it's fun, interesting and way better than school.
