The only genuinely misogynist people that I know of are so due to abuse. Mostly severe, over a long period of time, and/or by multiple perpetrators so it can be difficult to counter, especially when people’s response would only make things worse. So when it comes to misogyny I’d say that none of it is biological, as it goes against humanity’s gynocentric nature.

As for whether there is any non-biological reason for misandry; considering that women’s innate fear of men which often progresses to hatred (a side effect of the lack of empathy for them which is itself a side effect of their own self preservation), is biological, probably not.

Some say that the reason men are considered to be violent/rapists is because of biology but when perpetration by one sex is exaggerated while the other is ignored coupled with female preference it’s difficult to really know for sure with more severe forms of violence. Women are more willing to hit men than the other way around, it also takes a hell of a lot less provocation. Most men won’t report any abuse by women, emotional, physical or sexual. This perpetuates the idea that men are perpetrators and women are victims while encouraging women more inclined towards these behaviours to commit them. Believing that men can’t be victims while women can’t be perpetrators only increases those very things.

Something I find rather convenient is that with powerful men throughout history, people often say things like “behind every great man is a great woman” if what they did was considered good. They almost see what influence women can have over powerful men. Though they always seem to forget all about it when it comes to dictators, tyrants and despots.
