Why is it surprising that a massive influx of migrants from culturally backwards parts of the world could be a net negative for European society?
When you have uncontrolled migration from these parts of the world at these levels it creates ghetto's where integration is not only unlikely, it's impossible. Certainly there could have been a better solution for genuine refugees through the creation of safe zones within their own countries and a flat out you're being deported if you show up to Europe illegally. Immigration must be limited and legal, otherwise we will have more of what we're looking at now which is the rise of populism and empowerment of reactionaries and the silencing/self censorship of the press.
