I dont know, stockholm syndrome exists and I feel like its very relevant in modern society considering how many people are bootlickers for their employers.
I agree that people with an anti humanistic worldview being able to network is very dangerous. But most polarization I've personally witnessed are people not wanting to live in a system that heavily favors the rich without forcing them to contribute in the same amount poorer people do. People just wanna buy houses and be able to afford a family, while houses are being used as speculative objects by the rich.
That wouldn't create polarization, it would create extremely strong cohesion since everyone else enslaved by those tyrants would agree with you.
