Hmmm, women are sexually abused and subject to body shaming all the time, too, so I’m not really sure these are “reasons”.  I think it is more like these men feel entitled to more than they are being given by society and they lash out.  All of these are components of our patriarchal society, honestly.  That’s the root cause IMO.

You’re on the right track. I’m sure it’s in the study, but about 60% of mass shooters have some sort of history of violence towards women or domestic abuse. That’s the main idea of a “red flag law” the issue in the US is that the democrats suck at marketing and the republicans are great at it. They can spin up hundreds of “they’re coming for your guns” fear stories w/o a counter because the democrats didn’t give it a poppy name or something that sticks out. A better name would be “if you beat your spouse or children, then you don’t get to own a firearm law”
