“Yes, you meant that ‘sex’ and ‘gender’ are “often used interchangeably in the English language”, which implies, if not basically states, that they’re the same thing, and they’re not.”
They are essentially the same thing and have been used that way throughout history. If you don’t believe me here is an article on the subject. If you are still too childish to admit your mistake take it up with the author. I’m through wasting time on someone who likes to argue for the sake of argument.
