It's an oxymoron.
Pornography naturalises the subjugation of women - it treats them as less than human, and as demanding to be treated as such. The men are aggressors - they take, fuck, dominate and cum on or in as a statement of possession, as a cat would piss to mark its territory. Feminism's efforts to advance sexual equality, with both men and women treated humanely as human beings, sets it at odds with such abuses.
Feminist pornographer? We're in the domain of the moronic there.
