People died in Natzy camps because other people took the position of "it's not my problem"... An action is extremist or not depending on consequences and context. I know, as a fellow European, it's easier to not care when the people suffering happen to come from places like the Middle East or Africa. But this is just a bias to overcome. Probably real solution is that Western European countries actually update their police and legal systems to the point that they can handle the problem of more and harder to "herd" people. If there really are "no-go zones" in a country, then imo that's just police incompetence/complacency - they are paid from your tax money especially to prevent stuff like this from happening. More police and more prisons (and an upgraded legal machine to promptly prosecute thieves and rapists etc.) doesn't sound good, but it's kind of what you need to keep a safe society in the context of wandering masses of people with different values that need to be coerced a little into accepting democratical and liberal values...
