Agree that "psychiatric" drugs play a huge role, but mho is that it isn't just that. Or maybe it's an aggravating factor.
All of the "boy bad- girls good", reverse bullying wrt to gay/ straight, anti-racism, & now, "white privilege" bs- white male children are bombarded with guilt & conditioned to self-loathing from the time they start school & in the media. Because of the way they were born & stuff that they cannot change (gender, skin color, social status) They're being mind****ed (please pardon me) seven ways to Sunday. I'm surprised there aren't more kids/ young adults flipping out.
Really. What (more) have they got to lose?
The ones that aren't chimpin' out are staying home, not able to find work, not starting families. They're burying themselves in gaming & "social media" instead.
