The first name.that came.to my mind for someone like that was Hugo Schwyzer (I'm probably spelling that wrong) - he was very much a very outspoken feminist who made a point of drawing attention to how feminist he was at every opportunity. He was also a women's studies professor.
Honestly, some of his writing gave me the vibe of what it would sound like if you were a recovering addict and chose feminism as the higher power in your 12 step program.
Eventually it comes out that he nearly decided to murder-suicide an ex, and that he was a women's studies professor because it gave him access to an ever rotating stable of young, impressionable women to hook up with.
When he admitted to all that the wording again reminded me of 12 step program talk, like he was taking steps 5-7 publicly online because online feminism was the God he believed in for the program. It...didn't get the response I think he hoped for. Less absolution and more ostracism and banishment.
