The psychology of anti-feminist men is absurdly simple and straight forward: they hate strong, confident, intelligent women because there is no way in hell they would ever meet the standards of such women and they wouldn't know what to do with such a woman if they 'had' her.
That's really all there is to it. They view the feminist goal of raising the consciousness and confidence of all women as an existential threat. The less insecure, submissive women with low standards out there the less women even conceivably sexually available to them.
That's why the one big idea of the so-called 'pick up artists' is 'negging', attacking the confidence of women with putdowns and self esteem crushing remarks - its very revealing; they are flat out admitting with this tactic that no woman with any self esteem will have anything to do with them so they need to crush it.
