Male feminist writers

how bout Alexander McCall Smith's NO 1 Ladies Detective Agency

Not sure what would qualify as a feminist writer. Is this someone who writes with strong female characters and addresses systematic discrimination? There are a couple of sci fi writers you could read, David Weber (Honor Harrington novels) and Modesitt whose fantasy novels routinely point out discrimination against women in the medieval cultures he creates.

"Is this someone who writes with strong female characters and addresses systematic discrimination?"
Exactly.

I didn't pick up on that with Modesitt. I do read his stuff, though I sometimes confuse him with Harry Turtledove.
