I so agree! It's crazy how many guys I come across who are sure this is just "masculine nature" and don't have the foggiest how mysandric that truly is. But, even when they do start to grapple with the fact that this is socialization, they are so self-identified with it, it's hard to leave behind, even when it's pointed out all the ways that it's harming men (as well as everyone else).
This was a valuable piece that I'm sticking into my library for future reference.
