Men on men violence is not women's fault and not women's issue.

Men not beating women and "being less masculine" (what does that even mean?) is not a fault, but a victory for both men and women.

Older men are very mentally fragile and emotional too, they just spending those emotions as agression, most often agression to weaker people - kids, younger men, women. This was always the case before, nothing changed. Only changes is that gender stereotypes were partially abolished, so women started doing "men's jobs" and men started wearing different colors and clothing - and it has nothing to do with feminism, Glam Rock, David Bowie and many men activists, who were fighting for this, are reason of it. Stop blaming women on everything!
