Earlier quoted context omitted.
The Brontes originally had to publish under male pseudonyms (or rather, pseudonyms of intentionally indeterminate sex). George Eliot is a male pseudonym. Jane Austen arguably wasn't considered serious literature until recent decades; previously her status was more similar to, say, Miss Read in that she was a writer of rather lightweight tales for mainly a female audience.
Perhaps we should republish Eliot under a female pseudonym? But yes, fair points, and I'm not disputing there was sexism! But to describe the situation as "male only" is overstating things significantly.
So, there is not reason to reprint male under female pseudonym. With exception od romantic literature, male pseudonym is not disadvantage at all.
But, my original point was that there is nothing strange or unusual about morality that is sexist in one way or the other, that was actually norm.
