I hate the word. I think it's too totalizing, and undermines the disparateness of distinct non-heterosexual populations. I can see how it would be politically useful, but I don't think we've fully "reclaimed" it in any sort of positive way.
Do we need terms and acronyms at all? Do we have any better alternatives? Is it okay to use the word queer in certain ways with certain groups of people? When?
As JB says: Discuss.
