1) I think that these men feel they have no power at all. Roughly 50% more women graduate from college than men now, and have been for about 10 years, and more women have been graduating college going back to the late 90's I believe. In a technological, knowledge based economy, many of these men are behind the 8 ball before they reach 25. This is not a sign of young men thinking they have power, this is a sign of many men giving up.
2) We don't need to like each other, but I don't think demonizing men, and especially young men, because they listen to Joe Rogan or don't have a girlfriend accomplishes anything. I think they have figured out they are struggling in life without libs calling them names.
3) Many young men are in crisis. Cultural and technological changes are creating dislocations and many of these men are having trouble getting started on their adult life. Attacking them just drives them to demagogues like Trump. This is a problem around the world, not just in America, and finding a place in our society for them should be something that liberals embrace.
4) The last 40 years have not been kind to the unskilled, working class men, and you are seeing that with the GenX working class in particular, which is very heavily Trump. I am not going full Fetterman and saying we should twist the country in knots to appease this group, but we need to recognize that there have been social and economic changes that have impacted them, and their families.
5) I think the corollary is true also. Democrats do much better with college-educated men, and that is a demo that Democrats should embrace rather than drive off. I don't care if they want to watch MMA or listen to Joe Rogan if they vote blue on Election Day.
