I love the British Queer as Folk. Though I think Russell T. Davies makes some colossally bad judgement calls sometimes, I have no problem with his handling or gender or race: i think is errors in judgement are random and non-targeted.

when recently outed Nathan gets into a teenage rant at his (black and female) best friend about her belonging to the "heterosexual fascist majority", she pwns him by saying "I'm black, and I'm a girl; try that for a day". Exit Nathan, silent and stunned

I wouldn't mind seeing this as a conversation with Martha or Toshiko. Though I can't imagine it being Captain Jack in the male role; he's an outsider so far beyond the norm that he couldn't even conceive that rant. Ianto or Owen, maybe.
