Our entire society is geared towards statism, which = scientism.
Leftism is a borg. Populist right get sucked in but are willing to dissent because “the science”/“the state” don’t occupy their religious hole whereas that’s entirely true for the populist left.
Bigger issue I see is that the leftists have completely foregone reason, rationality, and logic. They are simply imbued with opinions via narrative and question none of it.
