To be honest, it sounds like another rant from a bored, isolated person, picking on insignificance, rather than seeing the bigger picture.
I have lost count of the number of different definations of transgender/transexual/trans and so on, I've read. Does it matter? If the aim of the piece is positive, why get picky over words, when most transgender people can't even agree?
The quickest route to ridicule seting up holy cows.
Edit. Removed reference to American Holly Cows. It wasn't intended to be a jibe at Americans, whom I respect, but rather a comparison with holly cow issues.
But upon reflection it seems a tad inappropriate, not to mention, unnecessary.
