I'm German, we have extensively learned about these twelve years in school. Trust us Germans on our experience with Nazism to say that it must be stopped in its roots before it gets hold and storms your Capitol.
Anti-revolutionary, infidel, morally corrupt and other words.
I am very scared of the Nazis (I also have other reasons to be scared of them because of the color of my skin, etc), but I am more scared of labels and people who apply those labels without a proper legal process.
Trust me!
The current leaders should always remember while kicking the weak ones today. How much bitterness and hatred am i sowing with my actions and who will reap the horrors. Same goes with the people on either side that cheer whenever authoritarian actions take place. They could be cheering their own destruction or of future generations.
By listening to what they say, what they want and whom they follow and analyzing that. People claiming that "a secret cabal of Jews" or whatever is trying to introduce a "new world order" via the coronavirus pandemic, or that Black people or immigrants are the root cause of an economic crisis are most likely Nazi sympathizers.
