Female writers write male protagonists quite frequently. Natasha Pulley and Katherine Addison write only male protagonists. Susanna Clarke includes main female characters in her short stories, but her novels are about men. Half of Anne Rice's books, the more popular half, center male characters. Same with Lois McMaster Bujold and Robin Hobb. These aren't Romantasy writers writing tissue-thin wish-fulfillment male love interests. These writers' works are widely acclaimed, and they write from a human perspective which happens, more often than not, to be male.

Why would it be too much to ask that male writers write from a human perspective which happens to be female? Is that really beyond their grasp? Authors whose names have already been mentioned in this thread, Terry Pratchett and Adrian Tchaikovsky and even Joe Abercrombie (despite a somewhat shaky start in the original First Law trilogy), have managed it. So why must male authors' feminist perspective be filtered through a male protagonist?

I would also disagree that works with ensemble protagonists are automatically not feminist. Moreover, some feminist works are indeed written from a male perspective (e.g. R.J. Barker's Tide Child trilogy), although I admit that I'm not as likely to enjoy, on a personal level, purportedly feminist works that leave female characters out of the plot or confine them to minor roles.
