The declaration, "trans-women are women" is self contradictory.

The declaration, "trans-women are women" is self contradictory. If trans-women were women, you wouldn't be able to identify them as something different. You would just say "women are women."

But the fact that you can differentiate them in such a way as to say "trans-women are women" in itself shows they are different from biological women.

Women are women and trans-women are trans-women.

This is so obvious as to be painful to type. Biological women were born women. Trans-women were born men and transitioned into a woman.

There's a clear, identifiable difference between the two. How the hell is this controversial?
