You should stop refering to middle school biology and check out university biology. And maybe also stop refering to outdated knowledge that’s been disproven.

There are about as much intersexuated humans as they are redheads.

Lots of species only have “1 sex” since they reproduce asexually (including some neat lizards).

Fungi went a bit overboards and you’d lack fingers to count most of them.

It’s like imaginary numbers, stuff is always a little more complicated than you were taught in middle school :)

Except for the hundreds of millions of species of lifeforms for which male and female biological sex is not part of their biology. But what do PhDs know about biology? they just scientifically study the core tenets of life.

Ok, since you’re the expert, what defines gender?

You are so objectively wrong… and fortunately for me: I don’t have to listen to you, and will now use that authority to make others not have to listen to you for you violated the civility rule of the instance!

Biologically incorrect.
