Do you think Nazis advocated for totalitarianism and genocide before they came to power? It was gradual and dog whistled, just like those 5 to 10 Republicans are doing today.
I’d say the only thing that has been so thoroughly beaten into people’s minds is what you’re having trouble getting past; the myth that the Nazis went full insane before they had total power.
The truth is that it was just like today: demonizing all minorities and blaming them for all of society’s problems while downplaying the calls for, and acts of, violence.
We’re seeing 1920 to 1932 Nazi party, attempted takeover and all, and those of us who see it for what it is are trying to stop them from becoming post-1932 Nazi party, the one you’re afraid of.
