This would make this organization part of what's known as the "Manosphere " which is a not entirely online culture of men, of all walks of life and races, who basically hate women, think women exist for the pleasure of men, and uphold and attempt to reinforce the worst aspects of patriarchy. Incels, MGTOWs, PUAs, and mainstream misogynists are all involved in this semi-organized online spaces.

For backstory on the Manosphere Od ask you to visit the website We Hunted the Mammoth. It's defunct now but you can look through its back catalog and get some idea of what these spaces were like, without subjecting yourself directly to them. They are prevalent on every social platform, and not just Facebook.l
