Are you unwilling or unable to understand it; Homosexuals. Don't. Have. A. Problem. With. The. Word. "Queer".
I'm not gay, but will say that it was pretty off-putting to me, reading the synopsis. Can call yourselves whatever you want, but if the book was looking for any more mainstream attention than just the gay community, better phrasing could probably been used. If the intended audience is only gays, and then only ones interested in it from a scholarly perspective, fine, but that's a pretty small market, I'd imagine.
First, the synopsis just used the word A LOT. Once or twice probably wouldn't have been so bad, but it was there enough to be noticible, which struck me as odd. And again, others may well be fine with it, but it struck me as out of place, and turned me off to any further interest. To me personally, it read about the same as if it had been saying it was about "fag relationships" in Star Trek. Another word that's used plenty in the communities, but just as out of place in the sentence...
In the context of the writing, i was expecting to see things described as either 'homosexual', or 'same-sex', i suppose.
