I think I was fairly clear, it is a binary system that has some rare exceptions.
Saying sex is a binary is saying there are only males and only females.
In healthy examples of mammals where development has occurred normally this is true.
This whole ‘its a spectrum’ argument is like saying humans aren’t bipedal, there’s a spectrum because some people are born without legs! It doesn’t make any sense.
That doesn’t mean that society should refuse to accept, include and support people born without the ability to walk.
It helps if you read and comprehend the comment chain to understand what is being discussed before you jump in with ‘I didn’t say that’ when I never claimed you did.
I don’t see why it’s so hard for you to actually read the comment chain. It is right there. You can re-read it at any time.
