It isn’t about promiscuity. It is about the bald use of sex to obtain power, and by direct extension, money that is at issue.
Women who aren’t affirmative action hires, who worked hard to get to where they are on their own merits, would be justifiably angry at someone like Kamala Harris, because the brush she is painted with splashes onto them.
It isn’t any surprise that calls to her campaign about her position on legalizing prostitution (euphemistically called “sex workers”) which she publicly endorsed in 2019, went unanswered.
I understand the point and see it as important, but I am a man, I don’t think this is moving women, and a bunch of republican men harping on it continuously may even turn off some women, perhaps a lot of women, while it takes up space that could be used to sell them on something that might win their vote.
