Now I have to see Marwen. As a male, I think that toxic masculinity is more cultural toxicity. This condition is not biological, but the rules that have been ingrained by “Western” (or at least American) culture over the last 100+ years. We have adopted an unreal caveman ideology as to the roles of gender, and it makes the world more dangerous.
Manliness has not always meant brutish domination of the world and its inhabitants.
