Personally, I have no issue with using the term "male feminist." It says to me that the person is a man, who believes in feminism's ideals.
I understand the opinions of all of the posters, but at this point, I think I have a bit of "language fatigue."
My classes are over for the year and I think I need a break from "The People's Republic of Cambridge..." But not a break from meeting my friends for drinks on Thursday.
