As somebody who is actually IN the community and hangs pout with real "queers" I can tell you that queer is NOT a pejorative anymore. We have taken it back.
I can also tell you that those who are out and vocal in said community don't have a problem with CD's per se, but they DO have a problem with closeted people in general. Especially those that want the fellowship of the community when they're in the mood, but deny them at every opportunity so as not to out themselves. The animus towards CD's is mostly about their secretive, closeted nature coupled with the fact that most of them are militantly straight. I have many straight friends and I didn't know most of them were straight until I'd known them for awhile. Those that are comfortably straight rarely announce it, unlike the average CD'r.
