Given your posts in the NJ UFO thread, you seem like the type who's skeptical of government authority and doesn't take a shine to the government dictating your life. Am I correct on that assumption, based on that posting history?
What if I were to tell you that in this bolded sentence, you're ceding to the government an immense amount of power to a central authority over an extremely personal thing that you take for granted with the comforting knowledge your gender expression conforms to the wishes of the ruling regime?
If you're a religious person, consider that you are imposing a "man's natural order" mindset on God's glorious creation in all its various permutations where the combination of X & Y chromosomes and the infinite mix of hormones allows for (nay, insists on) an astonishing spectrum of possibilities. If you're a nonreligious person, simply replace "God" with "universe."
Now, consider this question:
Who the fuck are you or this government to impose this simplistic, black-and-white, or binomial stricture on a fluid, dynamic, and infinite reality, and under what authority?
Authority. You're giving it away, freely, willingly, an immense amount of it, and that has wide fucking implications for those of us who are just plain old straight vanilla. And it's not because I fear the government suddenly misgendering me, but I do fear one that is emboldened to start making all kinds of other judgments and rulings over other parts of my personal life and right to privacy.
Sure, right now, their focus is on this one small group of people, of which a vanishingly tiny subset play competitive sports. Like Brisket said, the number in NCAA sports is in the single digits. That's your stated concern, right? "Men" playing in "women's" sports.
Why the fuck do you or anyone wish to turn this trivial sports shit that can be (and is) taken care of by the governing body of that sport into some epic, gargantuan fucking issue and place it into the hands of one old man? Do you understand what kind of power you're ceding to a singular individual who has demonstrated throughout his life that he thinks no one can contain his insatiable desire for more?
Have you not picked up on the fact that he has a habit of slicing us up into all these little minority interest groups and individually picking them out for abuse?
If you already understood all that and voted for the man anyway, you are undeniably fascist adjacent, at the very least, and have enabled a dictator. If you didn't grasp this shit, open your fucking eyes.
