If it is futile, let them do it. It would have no impact on you. But if it is not, then we'll see.

Also, I'm not so sure the republican men won't care. Usually, the more sexist the men, the more angry he becomes when women do their thing whatever it is even if it has no impact whatsoever for them.

As for them not interested? Well, some men only care about the women looking hot. Their ideas and feelings are irrelevant. So if a feminist is beautiful because she is young and happens to have inherited good genes, they would want to sleep with her. When not to seduce her, date, "train her to be a good girlfriend and future wife" and so on. Since they see women as inferior and "pets", well, "they only need a strong men who correct them". Which is why many, many young sexist men lie in dating apps about their political ideas. Or why they talk about how it is "unfair" that locker room talk is taking into account when dealing with them. Not to mention the men who "are no sexist" but "might or maight not" do anything when other men do sexist comments or things.

At the end of the day, those women might not be in a good place to date now and that is ok. It is better that they don't. Or that they wait until they can trust someone and feel safe. Right now, they don't feel safe.

And if "liberal men" suddently notice that they are having less sex because of that and are "hurt", maybe they can do things so those women feel safe again. But of their support depends on women sleeping with them, well, maybe they didn't supported them that well or enough.

It all comes down to USA is unsafe for women now, so women are withdrawing from relationships where they feel unsafe. Seems rational to me.
