I remember the American Legion actually fighting with the America Firsters. The America Firsters were isolationists and somewhat responsible for fighting America's preparation for WWII. The America-Firsters were real and bad news,
"Bad news?" Why, because FDR warmonger smeared and slandered them because they were in the way of his agenda of pushing America into the war?
FDR used a lot of the same tactics that modern Democrats use against Trump: lies, slander, demonization. If you were against going to war, then you were a Nazi. Now Trump is a tool of Vladimir Putin and anyone who supports him is a traitor.
Democrats never change their stripes. They have always been scum.
