Its a little unexpected when it happens, but some of it is surprisingly good. Many of the paintings by political artist Charles Moffat for example.
Another example is the untitled piece by Cuban artist José Gómez Fresquet (Frémez) below, done circa 1970.

Fresquet made the poster (silkscreen on paper 18 3/8 x 24 1/8 inches) around 1970 as an antiwar statement in solidarity with Vietnamese women. The poster’s minimalist approach (a la Che Guevara posters) makes the connection between the objectification of women and violence against women, while also bringing up race and class issues.
The poster later was popularized and reprinted in the United States by the Chicago Women’s Graphic Collective.
So its an important piece about a feminist issue. It doesn't matter if its done by a man. All that proves is that at least some men are on the right track. Its progress.
