Actually going to side with mrebo on this. Sometimes, being put under a community label leads to people assuming I embody negative stereotypes in the homosexual "community" that I deplore.
That's not to say I don't support people who use such labeling as a way of advocacy, but there are many drawbacks to it too - especially when it's forced on you.
off-topic: Reegar, I had an avatar of Spike a couple of years back and didn't think anyone got it. Glad to see someone gets my user tagline.
