„Woman“ in your mind is the only societal category which is completely devoid of external attributes.

I can not be a baseball player without playing baseball. I can not be German without being born in Germany. I can not be of color without the needed heritage or a certain amount of melanin in my skin. I can not choose to be tall. I can not choose to be male without being male.

It just doesn‘t make sense. If the category is that loose, then why have it at all?
