None of the folks I know that lean leftward on the U. S. political spectrum hold such quasi-religious perspectives; they simply seek tp prevent the imposition of such quasi-religious beliefs onto themselves and theirs.
What I interpret is that the folks that you’re referring to always attempt to co-opt the legitimate historical grievances of others into their overarching cause and that some, particularly millennials and post-millennials, are susceptible to their ‘persuasion’ and methods.
As one, “Boomer”, ‘leftist’ observed, “the revolution will not be televised”. However, millennials and post-millennials seem to not understand that this applies, also, to all media of mass-media capitalism. They seem to ‘believe’ that real social, cultural, or political change can be accomplished through Twitter/X, Tik Tok, et c.!
