I would say what sets it apart is the undercurrent of anger and grievance combined with the self destructive beliefs that are prevalent in the community. It's men and boys who struggle to find acceptance and belonging, maybe even for reasons that are initially sympathetic. But instead of healthy self-reflection and feedback, they find a distorted understanding of themselves and masculinity that only reinforces their isolation.
This is just a caricature. It's like saying all women's spaces are bad because some female influencers tell their massive followings that men should pay for expensive shopping trips on the first date. This mischaracterisation through cherry picking is destructive.
