I honestly can't imagine how you could avoid exposure to any of the incredible amount of discontent in Europe right now.
European leaders have been importing millions(!) of people from incredibly violent, theocratic, illiterate, and regressive regions, to the detriment of peaceful, secular, educated, and liberal Europeans who are not socially or memetically equipped to handle such an influx of radically different and heavily indoctrinated people. European news media emphatically denies that anything bad is happening; "No, rape rates have only gone up a little bit! No, we're not putting a wall around the Eiffel Tower, it's an aesthetic perimeter! No, Sweden isn't banning christmas lights in public for Muslims; it's because we all of a sudden realize that street lights can't structurally support christmas lights!" Most people in Europe are not dumb enough to fall for this.
For decades, the sentiment in the European political system has been "us last". Here's a great quote from the President of the EU Parliament until earlier this year, Martin Schulz: (and yes, it's a real quote): "For me, the new Germany exists only in order to ensure the existence of the State of Israel and the Jewish people."
The conclusion that any impartial observer would make is that European politicians don't seem to give much of a shit about Europeans, and instead see them as more of a resource to be used up for the sake of various political causes (mass immigration is a big one, and as Mr. Schulz demonstrated, Zionism is another).
It should come as exactly zero surprise that, at some point, Europeans are going to get fed up with being treated like shit by their own political system.
I'm not even European, but this sentiment is very obvious to me from my European expat friends. A large number of them are in support of leaving the EU in favor of increased national sovereignty (because then at least their own interests might come into play), and those that want to stay in the EU mostly feel that way because they falsely conflate free movement and free trade with the existence of the EU.
The result of this discontent with (forced) social globalism is that countries are becoming more isolationist. This led to Brexit, will possibly lead to France leaving the EU as well (although the EU parliament is currently trying to attack Le Pen), and who knows what next.
To be clear, I'm not happy about any of this, but I honestly don't know how people didn't see it coming.
