I don't know if "hate" is the right word, but young men without perspective are literally the worst group of people. They are a burden to society and the reason why immigrants and refugees are so frowned upon - they are disproportionally young male losers and those are much more likely to be criminal, especially physically.
The correct solution is to provide those men a perspective, the worst solution is to do what right wing populists do and tell them somebody else (like DEI, wokeness, the women who do not want to sleep with them) is the problem for their woes. Where is the party of personal responsibilitiy?
Charlie Kirk's message to young men was that they should reject a culture trying to lull them into eternal adolesence. That they should take responsibility, get married, get a job, have kids, be a productive member of society- instead of being self indulgent and indolent. That was his perspective and why he kept picking up followers at colleges. Why young men list their #1 priority to have kids when it doesnt even break top 5 for young women.
Who do you think shot him? If I throw a bunch of labels out, how many would turn out true of: Transgender, NEET adult, unmarried, no kids, self obsessed and delusions of grandeur.
