Arrogance and ignorance coming together as usual.
There are several native american and oriental cultures which have non-binary gender systems. Please dedicate some time to investigate, get out of that shell, and think before being arrogant.
The last line of the comment was aiming to bring my point across (which seems to have failed) - people do not need to label themselves as anything in order to be who they are.
Please re-read my post with a little more of a light heart - the sooner we all stop defining ourselves (and others) so seriously as members of tribes old and new, the sooner we can all speak to each other on a level playing field.
