Speaking of NEMESIS, it's the only Trek film to be written by an LGBT figure (John Logan), unless I'm forgetting anyone else?
Also, that line by Data does actually sound like a rephrasing of a line by Odo in "If Wishes Were Horses" where he's at Quarks trying to get everyone's attention, "Ladies, and gentlemen, and all androgynous creatures... Your attention, please!"
Well, LGBT people can be transphobic, but I still believe it was just an honest misstep on his part, assuming he even wrote that line as spoken, unless there's evidence that it wasn't.
