The conversations involve examining how the resources in society are allocated, and who gets to make those decisions. Both of these have great influence over our societies, and so much of toxic masculinity lies downstream from them.
I just don't see how this has anything to do with masculinity in particular.
There exists toxic masculinity in liberal left and in anticapitalist circles as well.
Masculinity is a social concept, which makes it inextricably linked to how societies are governed and how resources are allocated within them.
There are other aspects to masculinity that are not neatly confined to such terms, but a lot of the toxicity stems from the social aspects--primarily how we perceive, and talk about, men.
