any halfway decent student of history should be able to identify ways that oppressive countercultural movements or groups can be inspired by hegemonic oppressive social dynamics.
for example The People’s Temple led by the infamous Jim Jones in the 1950s-1970s and the Black Hammer Party in the 2010s-2020s were both founded in part on principles of anti-racism and socialism, which of course were responses to the white supremacist capitalist society that the founders lived in.
Those groups engaged in ruthless oppression of their own membership, which was due to the organizational and social structure of those groups.
Decentralized subcultures like trans-exclusionary radical feminism also formed in response to oppressive social dynamics, namely the oppression of cisgender women. TERFs selected a scapegoat outgroup (transgender women and nonbinary transfems) and focused their vitriol primarily at that group, even though the scapegoat outgroup (transgender women and nonbinary transfems) did not produce the oppressive social conditions which gave rise to TERFism or even feminism in general.
The existence of an external threat, an externally-created oppressive social dynamic, can be continually used by an oppressive countercultural group as a reason to exist, a uniting principle, even if their “solution” to the problem does not work or even make logical sense. People can make themselves believe things that do not make logical sense so long as there is some psychological benefit to them. The benefit could be religious/philosophical affirmation, a social ingroup, or a moral palliative that allows them to unburden themselves from the inevitable feelings of discomfort that arise from being friends with pedophile apologists and rape culture cheerleaders.
