Socialism is a deeply religious belief. It has its priests (professors, journalists, entertainers), its churches (campuses, museums, protests and benefit rallies as outdoor/big tent revival analog), its core beliefs predicated on faith that unite the fervent and ostracize the skeptical (diversity is always beneficial, climate change is the fault of the successful, racism is original sin, privilege creates winners and losers in spite of actual value, religions of the oppressed are blameless, etc.), and its intangible and perpetually just beyond The horizon utopia. In every important way, socialism is a religion. It has a general hate for "gods" which functions as a smoke screen for the incorporation of American Protestantism into its modern day Progressive skin suit.
You can see the energy of the faithful when technical questions are provided emotional responses, when differing opinions about generalities are met with personal assertions regarding psychological well being ('burn the hetetic' transmogrified into 'you need medical attention because you have (x)-pathy), and, always everpresent in Leftward arguments,appeals to authority that the one appealing doesn't recognize.
