Personally, this gray area of what's truly fair in competition when one is transgendered leaves too many variables on the table to determine the truth.  There was a transgendered motocross racer who managed to get into the woman's MX class, and he/she was cleaning house.  There's a noticable difference between speed on an MX track between the best men and the best women.  He/she was displaying the type of speed found more so in the men's class.   I have no dog in the fight anymore, but if my daughter was racing in that class, you're darn right I'd be ticked off.
