A lot of shit-flinging in this thread so fast. Entertaining, but man, how fast this devolved, lol.
Semi-serious answer, but I think it’s related to modern living in the West as an (employed) male at a large corporation. Many get talked-down to by managers, customers, coworkers (who are increasingly women, an important point I’ll get back to later)and generally have to be yes-men, follow the orders w/o pushback, good little wage drones/salarymen. These are seen as being “submissive” by some (I see it as not being a dumbass and needlessly rocking the boat but to each their own). Sometimes, people in their private/dating/sexual lives are opposite their public/professional lives (either to let off steam or to explore things they can’t otherwise). Men can have some tiny iota of authority or feeling like they’re special/needed/wise, which scratches an itch in men that modern life seldom does.
The deepest-seated thing about men in my experience (if they aren’t a narcissist or sheltered NEET) is the desire to be a provider. Having a career and/or authority gives that feeling and worth in a relationship. However, when men see women who are smarter, richer, and having more authority than them, they feel inadequate. “Why the hell am I needed? What can I offer that she doesn’t have?”
So a TLDR, I don’t think men like dumb women per se. Our primate brains want to feel like we’re providing and bringing something into the relationship, which for some men manifests the way you’re seeing it. Pretending to be dumb is dishonest though and an ultimate relationship killer as others have said, so avoid that.
Or maybe I’m wrong and thinking too hard/autistically about this. This thread should be in Deep Thoughts…
