Human and humanity are not the same thing.

Human is what you are. Genetics. Nature.

Humanity is how you behave. Thinking, programming, reacting to life experiences. Nurture.

Genetics = what you are.

Nurture = who you are.

One literally has nothing to do with the other unless you let it.

If you are pushing that male or female are who your are then you are a white supremacist pushing Eugenics.

If you are influencing children to have major surgeries or to take drugs for some sex change then you should be shot in the head.
