Sure, you can construe freedom to mean that someone who is male can claim to be female, or vice versa. It seems that some stretch this point to mean that freedom somehow means that you can be the opposite of your actual sex, if you so identify, but now we're veering off into a wrong-wing Twilight Zone, where such a twisted version of “freedom” is held to trump provable truth—that somehow one can achieve “freedom” from the hard, immutable rules of science and biology. Somewhere not much deeper into this wrong-wing Twilight Zone, will be those who believe that they can step off of a cliff and just hang there in the air, because they demand “freedom” from the law of gravity.
If we will not acknowledge that those who claim “freedom” from obvious science, biology, and physics, are delusionally insane, and in need of psychiatric treatment; then surely we must still acknowledge that sane people are not under any obligation to recognize these delusions as truth, to play along with them, or least of all, to grant legal or social privileges based on them. Women, for example, are not under any obligation to tolerate the intrusion of a man into their restrooms or dressing facilities, jsut because this man “identifies” as female, even if he has had himself surgically-mutilated to conform to this delusion.
