I think you’re confused. The men’s lib community is a progressive, feminist-supporting space focused on giving men an opportunity to discuss matters of vulnerability and struggle. They try to help people struggling with mental issues hard times, and discuss how to counter toxic masculinity type shit.
I’m not involved in the Lemmy community but I used to check out the Reddit one back when I still got on there. The toxic neckbeard shit that’s up in arms about the overblown man v bear shit is the MRA (“men’s rights”) group.
