You know, thinking it over and reading (some of) the above, I find that I do feel a sense of responsibility for representing the communities to which I belong.
I mean, people know I'm an alcoholic in recovery; if I act a dry drunk and mistreat people the same as I did when I was a wet drunk, I'm not representing the community of twelve-step programs very well, and that brings me to reconsider my behavior. At the same time, people know I'm gay, and if I'm an asshole I make the gay community look less attractive than it should be.
But I have never believed that being effeminate, or even outrageously over-the-top effeminate, misrepresents the gay community. The gay community represents, to me, the freedom to be what I am despite the dominant paradigm. Whether what I am is a trucker who likes to make lace doilies or a transvestite who likes to whittle, I do so loudly and proudly and publicly, because being able to express myself naturally and freely is the essence of the gay community... and that is what I want to represent.
Being selfish, being drugged-up, being sarcastic, being vicious, being a user of people and their things... that misrepresents. So when I'm being very visible, seven feet of drag queen in red hair and sequins and more rhinestones than a Vegas showgirls would dare to wear at once, I am aware that I am representing my community, and so I make more of an effort to be kind, supportive, and useful to that community. I want people to look at me and say "Hey, that Miss Marlénè Manners is pretty nice... maybe drag queens aren't as bad as I was led to believe."
I have no respect for people who would look down on me because I do drag; but there are simple human mores that I feel it imperative that we follow, especially the more visible of us. There's nothing worse than a mean queen, you know? They let down the outside and the inside of this community.
