This is how Hitler sold anti-semitism...create a narrative that certain Jews were bad, and then create a second narrative that lumped all Jews together.
Some things never change.
Actually, Hitler did not create a narrative that some Jews were bad. He said all Jews were bad right out of the gate in
Mein Kampf. He talked about "world concepts" and then explained what he believed the world concept of Jews was, and that their concept was centered around Marxism.
That is the point when I saw two dangers approaching. Previously, I did not truly understand their names or their importance to the German people’s existence. Their names were Marxism and Jewry.
Hitler then devoted the bulk of his book explaining his own world concept based on race, and explained that Germany must become as violent as possible toward all races, as this was a law of Nature, and must fight wars to gain territory. He particularly aimed his warring vitriol at France.
Hitler was so out there that he even scorned the "racialist" movement in Germany for not being violent enough. And for that reason, he made it clear in his book he did not want to be called a racialist. He thought they were wimps.
So those people who say "Islam is a religion of violence", and thus paint ALL Muslims with the same brush, are very much in line with Hitler's way of thinking.
Today, if you aren't extreme enough for modern day Nazis, they call you a "cultural marxist".
