logically, there is always going to be two genders and that's male and female, I don't know if this thing about changing a person's gender is a social or mental construct. in my opinion, if someone is a male by birth but decides to become a female that's their choice but they should not play any sport with females that's totally out of line. imagine how chaotic it would when a transwoman competes with women in a game like boxing, wrestling and other sports that involves physical contact, changing gender doesn't change the fact that the athlete is a male.
I agree with you, gender change can never be social, it is completely created from a person's own mentality, as a result of which he changes gender. However, when a man transforms from a man to a woman, a man never actually becomes a woman. I think that women should be given the place of women and men should be given the place of men. If we are in wrestling or boxing and all the physical sports where women are with real women and men are with real men, then we can never expect discipline there, this is absolutely clear.
