In my experience at least, most Democrats and most Europeans have been brainwashed to the point that they completely believe (i.e. they have no doubt) that: (1) multiculturalism is good, (2) moral relativism is good, (3) unlimited tolerance and political correctness are good, (4) more government is a good thing, (5) less religion is good, and (5) judgment by individuals is bad but judgment by the media and the courts is good.
I am not alone in my opinion. Even liberal philosophers like the late Allan Bloom agree. The minds of Americans (following the path of European socialism) have been closed by dis-education and dis-information. Literally, they are unable to accept concepts different from what they have been taught for so long. Higher education as an institution has failed them, though they would reject that idea. It is hardly possible for so-called liberal Democrats (and even less so with European socialists) to imagine profiling a group of people who openly state their intention to harm Americans and this country. Europe is probably beyond the point of return.
I would love to hear a counter argument.
