If testosterone doesn't make men superior to women, then why are trans being banned from women's sports

Testosterone doesn't make men superior, just stronger. Men and women are optimized for different things. Also, women evolved color vision first so you can thank us for that.

When does the sky stop being the sky and just become the air we breathe?

If homosexuality isn’t a mental illness, then why were gay people institutionalized prior to the late 20th century?

Uuuuuhhh, testosterone DOES make men physically superior to women, testosterone is what makes men's muscles naturally better developed/stronger than women. That's why an average man athlete beats women in competitive sports, that's why trans women have been fucking over biological women and taking victories from them while never getting any when they competed as men.

Trans women do NOT have a place competing amongst biological women. Even if they go trough transition, even if they lower their testosterone they still have much more than the biggest butch lesbians.
