Wrong. Your article is specifically stating there are 2 biological sexes and makes a clear difference between biological sexes and genders there. This is the general consensus of scientists right now whether you like it or not. So debate it with them.
And another report i suppose since you dont stop with the libel. Also the irony is marvelous considering a quick search of yours would have told you that mate has become a gender neutral term since a longer while. Same applies to dude in fact. Also you have now proven that you have no idea how languages work given your phrase “both come from” not understanding that terms and languages changes over time. Try again.
