I’m not an expert on how Europeans think, but I wonder if the horrors of Nazism have anything to do with it.
The Nazis believed there was only one master race.
So the Europeans swung to a completely opposite belief: All cultures are exactly equal.
What those idiots don’t get is that the Muslims ARE today’s Nazis.
In my past jobs I met a number of well educated Europeans. The self-loathing of their culture was very apparent. Of course they thought their culture was still superior to anything USA. They couldn’t wrap their little heads around the idea that an educated American like myself could be proud of theirs.
