I certainly don't think the concerns regarding sport are transphobic, how could I possibly? I agree with them, I sadly don't think it works at all to have transwomen in female branches of sport, and I know I'm not a transphobe.

My issue is, always, and only, the angry language used, and the baseless assumptions made. "People born male have a natural physical advantage even after transition" is a valid and respectful criticism. "Men will deliberately pose as women to cheat!" - until it actually happens - is needless fear mongering. Much like the concept of rapists dubbing themselves Susan to get into hospital wards. You can call it a valid fear - all fears are valid in a sense - but its also entirely irrational.

Regardless, even if you see it as a valid opinion, you have to concede that someone holding that opinion is not an appropriate LGBT ambassador?
