>One style is to only masculine pronouns, another to only use feminine //

In English the neuter pronoun is identical to the masculine. "to stop him" doesn't assume that he is male nor female it is agnostic on this point. Unless there is some other indication of the sex of the subject being referred to then you can't necessarily tell. Of course the reason for the use of the masculine pronoun as the neuter is probably historically based in language education being mainly provided to men, but that doesn't mean it needs to be "corrected".

Excepting that point I think I'd agree with what you said.
