This is why some people insist on the generic he in English. A few hundred years ago, some British asshole who thought Latin was a perfect language decided to impose Latin rules on English, including such nonsense as “you can’t end a sentence with a preposition” and “never split infinitives”, as well as proscribing the then-common singular they in favor of “he”. The damage he did to the English language is still not fully repaired.
Even if they only succeed in doing a fraction of it, that’s still really fucking bad.
