Stop defending him. We don't only have his ex wife's word against him, we have the word of lots of other people, AND his writing. Which isn't all that feminist.
I like a female protagonist who kicks ass as much as the next feminist, but if the writer also uses rape for drama, et cetera, it is pretty obvious that the guy in question isn't really a feminist.
Yes, the headline "wife exposes him as fake feminist" is rather exaggerated, but that's because we know he is fake already from other sources.
