Things like universal healthcare and social safety nets have made people's lives better in other countries and would make people's lives better here. Having accessible mental health care would directly help men.
Universal healthcare and social safety nets are not (necessarily) socialism. All universal healthcare means is that everyone has a right to healthcare. Doesn't say how. The state could own the healthcare apparatus like the NHS, or it could be simply a private insurance mandate supplemented by plans for low-income individuals. Socialism just means that workers own the means of production. I agree that universal healthcare and a reasonable social safety net are both necessary.
Nobody on the left things that individual men have never been the victims of society - e.g. toxic masculinity.
I'm just curious, do you think toxic feminity is also a thing? Or just toxic masculinity? If both then I guess you're consistent, but I object to either label. I prefer the term "toxic gender expectations", especially because either gender can impose toxic expectations on the other or their own.
Also, most feminists do believe that even if men have ever been victims of injustice, men have never suffered because of their gender. They really love the term "patriarchy backfiring". Something which I think is a complete lie. Boko Haram's murdering of schoolboys is a perfect example. They let the girls go and burn the boys alive.
