Bit of a debate going on regarding the transgender issue in sport.
Laurel Hubbard the New Zealand weightlifter for example. Competing in the Olympics. I think if she were in with a chance of a medal it might have been a huge issue.
I might be wrong about this. But are the issues somewhat larger when it’s a man changing to a woman.
Indeed they are. The only issues infact, AFAIK?
Basically, mature men are stronger than mature women, post-puberty. They have stronger bones, stronger musculature, mainly due to having much higher levels of testosterone.
So a Trans woman who went through puberty as a male, will tend to be stronger than a genetic female of the same age. It doesn't really matter how hard a woman trains, the Trans woman will always have that advantage. Big efforts have been made to include Trans women in sport, mainly by getting them to take testosterone blockers to approach female levels (women do have some testosterone), but it's a very grey area to be able to say you put a Trans woman on a level playing field by doing that.
I have every respect for Trans women (God I've fucked enough of them and I love them like I love women) but IMO it's simply not fair to Cis-women to let Trans women compete against them. And that's despite my dislike of women's propensity to moan at just about anything, and to say men alway have it easier than they do. In this case they are right.
I'm not aware of any issues the other way round, I cannot imagine Trans men competing meaningfully with genetic men, although by adding exogenous testosterone they might get close. But then taking testosterone is actually doping, so not allowed in any case. I think the only problem might be shared changing rooms, if indeed that were considered a 'problem'
