See, I find that to be an assimilationist attitude in itself. I am not a str8 fruit-picker or coal miner. I'm not a terribly beset Appalachian single mother.

It depends on your vantage point. From the vantage point of professors like Audre Lorde, Myrna Bain, and other black lesbians in New York teaching gay liberation classes to mostly inner-city LGBT students at the City University of New York, this is more than theory. It is a very valid point of view that is not limited by our environment, but painfully reenforced by it on a daily basis.
Is it a surprise to anyone that class/race/gender issues should manifest themselves wihtin the LGBT community? No, it is not. What is a surprise is that gay people wouldn't take time to thoughtfully analyze not only the issues, but their actions.
