As a parent of 2 elite track and field athletes that train their asses off, this is bullshit, I'm sorry. My daughter in particular has shed a lot of blood, sweat, and tears to get to where she is. Would it be right for another elite athlete who has transitioned to race against her? She would be furious, as would I. The USATF and NCAA need to pull their heads out of their asses, testosterone levels are not an accurate indicator of anything. If you went through puberty as a male, you've deposited muscle in a way that can't be walked back with all the hormone treatment in the world. Its related to hip geometry, etc., which is completely different between men and women. This is science, pure and simple.
Its a free country, and you should be able to do whatever you need to for happiness and fulfillment, as long as its not at the expense of someone else's happiness. We all can't have what we want, there are sacrifices with everything, and if you transition from male to female, one of those sacrifices is you shouldn't be competing with the biological women. Its not right, and just not fair to every biological woman who is busting their asses and making sacrifices to be the best at what they're training for.
