Not to labour the point overly but on a recent relevant BBC radio prog, a point was made about athletes who were fortunate to have characteristics that help them succeed. And we enjoy their success.

Should we now have high jump events for different heights of people? Much like the Paralympics have numerous classes?
And there is a fear that if the prize is big enough there are athletes who would opt for surgery to give them some advantage. If you poo-poo the idea think again - is doping any different? At what age did FloJo die, and why?

Transgender in sport would come under this umbrella notion. I see no reason not to view it with that perspective.
