I've been trying to trace back the origin of the "conservatives are actual Nazi" mentality from the left and I see to have traced it back to Reagan.

It appears to have started during his administration that Democrats went from disagreeing with Republicans, to calling them the worst names they can think of and actually believing they're evil.

This was anecdotally confirmed when I spoke with my TDS riddled older neighbor and asked where the political divide originated and she immediately responded "Reagan" and his "trickle down economics".

What the fuck happened during this time period? Was it the media? Who were the thought leaders who started this crap? From my understanding 'trickle down economics' doesn't even exist... he just gave tax cuts to everyone.

I need to understand the origins of this. Thanks in advance

Update Seems to go back even further than Reagan to Goldwater in 1964.
