My experience on this topic is exactly opposite the initial assumption: Most of WW's fanbase is male, not female. Like 80%+, I'd guess. Which makes sense if you think of the historical demographics of cape comics. I haven't known a ton of comic fans in my life, but most of them were male. Several of them bought Wonder Woman comics on the regular. And Supergirl.
I've never known a woman who's been into Wonder Woman - on any level. Not even the TV show, which I watched reruns of as a kid. Within my own household, my daughters both love fantasy, superheroes, and both read comics and manga in their teens. But until the Gal Gadot movie, neither even remotely liked WW. My younger daughter always called her boring. But after watching the Gal Gadot movie, she said that version was "badass". She loves warrior characters. So...progress, I guess?
