Ellie showed me an interesting "Open Letter to My White Lesbian, Gay, Bisexual, Transgender Sisters and Brothers," by Diane Finnerty, "a 44 year old white lesbian of German/Irish descent." (The original version is a PDF that's better-formatted and easier to read, but I generally prefer to point to HTML versions where possible.)
The gist of it (though I'm way oversimplifying) is that the white GLBT community often engages in language and action that may alienate communities of color (and that even setting up that dichotomy between two monolithic "communities," as news stories often do and I just did, may be harmful), including using the rhetoric of the 1960s struggle for black civil rights without an understanding of the details.
I don't agree with all of the piece, and I think the language of it (starting with the side note in the first paragraph that takes for granted the notion that the US is turning into a corporate theocracy) is probably radical-liberal enough in tone to make some readers immediately disregard anything Finnerty has to say. Still, I think there's some valuable stuff here; good food for thought.
No time to discuss in more detail at the moment, though.
