Read bell hooks' "The Will to Change" to start. As someone on the far-left, we talk about positive masculinity all the time.
The whole concept of intersectional feminism is that there are different classes of privilege and exploitation that are relative to each other. To say that modern feminism doesn't think men are exploited is to misunderstand modern feminism.
Are young men exploited? Absolutely. They are exploited by capitalists to extract as much value out of their labor, their bodies be damned.
Are they exploited by people in power? Absolutely. The entire manosphere exploits their loneliness and keeps them isolated as emotionless rugged individuals.
Men are humans just as women are humans, and men have the same human need to connect and socialize. Toxic masculinity strips them of fulfilling that need.
Feminism gets caricatured so much by people who have something to benefit from that lampooning. Rather than dogpiling on the "feminism is mean to men" bandwagon, actually read modern feminist literature on masculinity.
It is more geared towards a group of trusted people communicated with each other than a general purpose network anyone can use.
