I have to agree with a lot of the comments that being "left out" may not be quite accurate as to how I feel about the recent transgender discussion. Personally, I am glad that the discussion is going on with the media et al recognizing that yes, there are people who choose or feel more comfortable presenting as a member of their opposite birth gender and telling the world "That's OK". But so far the discussion seems to be rather shallow and perhaps is creating a new stereotype and that is that transgender people want to constantly live as a member of the opposite gender - maybe with or without SRS. There is little or no conversation about gender fluid persons who cross between male and female mode but primarily retain the identity of their birth gender.
So now is the new stereotype of someone who is transgender a boy who is now a girl? (or vice versa) And presumably the boy who is now a girl likes all girly things? And has abandoned all boy things? And presumably does that "girl" like male partners as most girls do?
Bottom line, without some deeper public discussion, I'm not sure we are seeing a big step forward yet - and potentially a step backward - back to the presumption that we are all gay.
