It’s easy to get a following by fostering fear and hate. Literally just blame and vilify a group and blame them for all the problems your target audience has.
I do agree males are disproportionately impacted by certain things… look at prison, suicide, etc. but I also think feminism would correct that. I’m a truly equal society, men wouldn’t bare the brute of the stress of financial support, for example. I also think in a truly equal society, the notion that men chase women goes away. People are just out there trying to find love and/or happiness.
If you have that, a lot of the symptoms you mentioned, where men are disproportionately affected go away.
