I'd like to add that intent is what matters most for me. If someone here said the word, as we are, it doesn't bother me so much. If someone says it to mock or hurts someone, as it's happened to me, then I feel a different way. I guess the moral is just strive to be a good person and avoid trying to purposefully hurt someone else, at least that's my view.
As for Rupaul, I'm not against him doing his thing, but I wish he didn't try to speak for our entire community. Sure, he can be included in the broader transgender umbrella but he isn't a transsexual and should consider how we may feel about these things. Personally, I don't care what he says, but some do and maybe he should be a little sensitive to it, just like how people seem to be with other insulting words directed at marginalized groups.
