I am not necessarily disagreeing with your argument,just pointing to that your argument is actually referencing.
groupthink is a direct result of systems of indoctrination to inject a value system to tacitly accept the current power dynamics.to bow to "authority",and a complicit media that has become the guard dog FOR the powerful,rather than the watchdog OF the powerful.
many americans are under the impression,and wrongly I might add,that our republic is somehow immune to tyranny,despotic leadership and fascism.
we are not immune.
what we are witnessing on the extremes of the political spectrum are manifestations of their own flavor of groupthink,but they all are a direct result of indoctrination and propaganda.
socialism has little to do with that.
in fact,the knee jerk reactionary responses to "socialism" are a simply another form of "groupthink".
