The Nazis confiscated guns from the public. Today, Democrats are attempting to confiscate guns from the public.
The Nazis brainwashed Hitler Youth. Today, Democrats are brainwashing American kids in schools and colleges. A majority of college students today prefer socialism over capitalism.
As documented in Liberal Racism, FDR and his brain trust greatly admired Hitler and his fascist control.
Socialism/fascism is overweening government control. It is the opposite end of the political spectrum from libertarianism, as propounded by our Founding Fathers.
