What you’re describing is the etymology of the word, but its actual meaning in public discourse has morphed to “men who see women and any real or perceived slight/rejection from them as the source of all their problems and are thus generally - sometimes extremely - hateful towards them”.
One reason, maybe not the only one, could be that they’re being told it’s all lies or in any case untrustworthy reports, or hugely exaggerated. I’ve seen many examples of this.
