I'll give you an example, for twenty years red sonja is portrayed as a warrior who will only make sex with some one who can beat her in combat. That's a short list, so short red sonja is practically a warrior monk.
Gail gets her hands on red sonja and turns her into a turbo slut. Those arn't the words Gail uses, she calls red sonja an empowered woman secure with her sexuality that isn't afraid of consequences but the end result is the same. Literal splash pages of sonja using her hard won treasure on huge orgies, or berating a man she just met for not fucking her on the road because she smelled like a hobo's nut sack.
Personally I got a big kick out of red slut but to die hard red sonja fans it was a slap in the face of decades worth of stories just to push the feminist buzzword of the day, sexual liberation. And terrible, off putting sexual liberation. Just gross. (Again, I'm into that kinda thing so it doesn't bother me.)
The plasticfags are worried, maybe too much, but not with out reason.
