The BLM protests were the largest in US history. The fact is that most Americans have been coddled by a stable democracy and don't care if they lose it, as long as someone puts a buck in their pocket. They think it won't affect them because Congress bad, both sides bad.
Of the ones who do care, they think protests dOn'T wOrK because BLM or the Palestine protests failed. Completely ignoring the fact that other civil resistance movements have succeeded and are historically more successful than armed revolts against the upper class.
It was the generation after the Nazis that did all the work to redeem Germany. The Nazis themselves never admitted that what they did was wrong, even when it destroyed their own country.
And of course they felt free. To the mediocre, the hateful, and the weak-minded, "freedom" means power over others, and the Nazis gave their supporters a tiny bit of that power.
