Its really just women changing massively for no explicable reason(60% of all college degrees go to women) and maybe a small slight reactionary shift among men but its all blamed on misogyny.
It's wild that you can come up with an entire thesis on why men have moved slightly to the right, but it is completely beyond your comprehension why women may have moved sharply to the left in recent years.
There are reasons for young women to move left but a lot of them are garbage. Women form 60% of college degrees and yet for some reason as this trend continues liberals start believing women face discrimination in achieving college degrees ? Other reasons are self serving like most people do such as debt forgivable
Young Men either don't go to college or if they do they pick the degrees resulting in better jobs to pay off debt. Meanwhile young women join college and don't pay of their debt.
