Put differently, it’s not Harris’s campaign ads that are repelling men; it’s her female supporters.
This means we need to consider the typical leftist woman and what she values. These days, she is most likely unmarried, childless, nonreligious, loves abortion, and seeks regular affirmation from her tribe and political party. This is why Democrats go to great lengths to make women feel included, empowered, and comfortable, mainly through generating good vibes.
While effective in the short term, this pandering has consequences in the long term. Because the typical Democrat woman is constantly coddled by leftist institutions and indoctrinated with a radical feminist agenda, she is not the best person to bring men over to her way of thinking (or more accurately, feeling). She is not feminine, kind, fun, interesting, industrious, or logical — such qualities are simply lies propounded by the patriarchy. More often, she is unattractive, resentful, lazy, irrational, boring, and/or entitled.
Even if men might agree with certain leftist ideas and policies, most of them will have a hard time engaging with leftist women as such. In general, these are ones who reject marriage, children, and conventional beauty standards and don’t like men who aren’t over six feet tall, with a six-pack, and a salary over six figures. They want to compete with men, not complement them. And they seek submission from their lovers, not mutual sacrifice.
One doesn’t have to be a drooling devotee of Andrew Tate to be put off by all this. It’s perfectly normal and natural to value a woman’s beauty and virtue, and be the man they want to build a life with. At the moment, this dynamic seems to be more common in the conservative movement.
