Where do we draw the line?
Biologically, I believe--while there is no accepted term in the scientific community (..really? No specified term?)--that the line is drawn (..in context I guess) with the chromosomal origins-by biological status. The discussion on extra chromosomes however should be in another thread (I doubt they belong in the sad thread, because I really don't think its something to be sad about-I am unsure whether there are people bad enough to harass those who are with that kind of condition). The notes you refer to pertain to primary and secondary sex characteristics attributed to either gender--yet I think you're missing a few details. Note ahead, people aren't born with a complete (mature and functional) set of both sex organs. Sorry, but that just doesn't happen in humans. However, that said, intersex people are born with a mixture of male and female tissues. There are dozens of intersex conditions that range from ambiguous appearing to invisible.
Next, gender identity is a separate issue entirely. Intersex people, just like everyone else, identify as male or female. Gender identity is centered in the brain. Suggesting further personal research on the matter there, Allee. ;P It'll help. Also Gender =/= Sex.
However, psychologically-what the person chooses in full knowledge of his or her choice to be known as, is also acceptable if he/she knows the full scope of what he/she is claiming; an informed choice, that is to say.
In other words: You've arrived at a whole number of intersecting tangents that they'll soon form a circle when fully discussed.

You..never removed the bee. The whole time. o_o
Anyway: Sads.
Parents are away, and my puppy is shivering from the cold. It's lonely at home now. Just me and my pet. :/
