The gentleman in the video expressed the belief that misogyny is inborn, due to the way male brains are wired. If he's right, then I think it follows that, like anything that is inborn in us, it's not expressed the same way or to the same degree in every individual. I would see it as a continuum, from some brains lacking this defect to any discernible degree to some being wired to be extremely misogynistic.
Also, I believe the role models boys grow up with have a big impact. The effects of growing up in a violent home have been studied extensively, and if I'm not mistaken, experts generally agree that there's a lot of evidence that boys who grow up seeing male violence toward women as a regular occurrence are statistically more likely to be violent toward women as men, and girls who grow up witnessing that sort of thing are statistically more likely to expect that kind of behavior from men.
Personally, I think he may be on to something, but I wouldn't take it as far as he does. I don't think ALL men have brains that are miswired in a way that makes them inclined to hate and fear women. Some of them? That I could believe. I could also believe that many men have kinks in their wiring to a lesser extent. But I know for a fact that there are men who would never think of being violent toward women, because I've been married to one for over 50 years.
