You're wrong - the scary shit is the over-reaction to this that is putting fascists into positions of power.
Many ordinary apolitical Germans thought that the NSDAP were a bit over the top, but at least they were standing up to the Jews who threatened the very existence of Germany. The terrifying thing about the Nazis is not that they were such vile and monstrous thugs; It is that they were completely ordinary, everyday people, just like you or I, who simply blundered into totalitarianism because they were angry and scared. America and Britain are doing EXACTLY the same thing today - embracing nationalism as a cure for problems they don't understand, without stopping to consider the unintended and dangerous consequences.
Fucking hell. Why do folks always jump to Hitler? That's the only ridiculous analogy they can make. Several millennia of record human history - all they know is Hitler. There is no sense of proportionality at all. The Hitler comparison is so beyond stupid that it's difficult to take anyone who raises it seriously. Are there no original thoughts anymore?
Moreover, the point in my recent posts is that when Islam increases in a society, that society becomes less tolerant. Do you agree or disagree? A key difference beyond Hitler (because of the vast ignorance of all other human history) is that Hitler was a dictator, Islam is a political religion. Islam dictates what you can eat, believe, say, etc. If you leave Islam, that is license for others to kill you. Religions don't need dictators to make a society miserable. The adherents do that willingly.
