I don't care about sports that I have zero interest in, so I'm not to comment on those such as weightlifting, roller derby, MMA (never going to happen at the upper levels of the sport anyway), or Canadian masters cycling. For other track events, a couple of sprinters in a relatively non-competitive state that wouldn't have been eligible for scholarships and a D-2 hurdler does not bother me. Semenya and other intersex athletes, or those using PEDS, are not a topics applicable to this thread.
I don't believe becoming transgender has become become some type of fad. I have children in public schools and absolutely no one has approached them to encourage them to transgender and, of course, they wouldn't consider it for even a fraction of a second. If there are people are vulnerable to such influence, what do think the probability of them also being ultra-talented in distance running with the drive necessary to do the training?
Any change to the current rules will have to be litigated in court, and no one gives a crap what some people with PhDs think. I'm not aware of any public figure saying that untreated males should be allowed to compete against females. You providing some quotes from some absolute nuts, would not prove anything.
As I said before, no one is going to exploit the rules regarding hormone treatments. Taking the treatments is effectively becoming a woman and it would be devastating both physically and mentally. It's not as if they would be a woman on the track and a dude the rest of the time.
Here's the only part Biden's EO that addresses sports:
"children should be able to learn without worrying about whether they will be denied access to the restroom, the locker room, or school sports."
Why are people extrapolating it into the end of women's sports? "Children" do not attend college and although it is an extremely rare occurrence for there to be a HS transgender athlete, they are already allowed to compete "as-is" in most states. As I said before, Biden does not dictate NCAA rules.
