In the past in English "he" or "him" could mean a male or female
But "she" or "her" could only mean a female
There was no pronoun that included males while excluding females in English until feminists started complaining about the use of "he" or "him"
Is Females being able to enter male spaces but males being forbidden to enter female spaces a default assumption in English grammar because there is a grammatical way to exclude males but no easy grammatical way to exclude females with pronouns?
Male or Female -> He, Him, His
Female only -> She, her, her
Mailman, fireman, policeman, man, men, mankind -> Male or Female
Woman, Women -> Female only
English language defaults to letting women enter male spaces but excluding males from female only spaces
We should get rid of grammatical gender from words
We should just insert male or female to refer to biological gender as needed
Otherwise the language will encourage women invading male only spaces being acceptable in people's minds
