Frankly, it's a cult that exploits personal trauma and ressentiment by framing individuals as victims trapped in whatever "social prison" of systemic oppression of the proposed theory, fueling resentment  & dependence on the group for identity and purpose. 
It's a cult, and this dynamic sustains itself by amplifying victimhood and moral indignation, and also by isolating cult initiates from alternative perspectives, and preventing healing or growth. The result you see is profound personal damage: trauma is weaponized and used for bonding rather than addressed, fostering cycles of resentment and emotional dependency on the cult itself. It's awful, frankly.
