>the same could be said for race,
No it can't, what we regard as "race" are just phenotypes that are particularly striking to our sensibilities, you can't name me any "white" genes for instance, meanwhile women have a whole extra chromosome and can poop out kiddos.
>yet segregation by the category of race has been a huge failure,
can you see how that relates to sex as a category?
Haha another desperate attempt by transgender activists to equivocate racism with transphobia. Sorry, race was a social construct imposed on minorities by white supremacy, gender dysphoria is something trannies impose on themselves.
>"black people don't have blue eyes is as true" a statement as "women can't beat men in sports"
Hahahah having blue eyes or not is arbitrary compared to being able to give birth. This false equivocation is the only way transgender idealist non sense has any type of ground to stand on. You literally have to believe that someone having blue eyes, or curly hair, is the equivalent to someone that can give birth, and someone that can produce sperm lol.
