How should LGBTQ venues be tagged?

I’m thinking about how best to tag LGBTQ venues, (e.g. “gay bars”). And I’m not sure how to do it. I’ve started a thread on the tagging@ & diversity-talk@ list, and I’m asking here for advice.

Initially I thought lgbtq=yes was a good tag, but now I’m not sure. Does anyone have any advice for a way to tag them in keeping with the OSM tagging convenctions? lgbtq=designated, lgbtq=only, lgbtq=???
