THIS video shows why Europe is currently facing a rising tide of Nationalism, that is threatening to become more and more violent, the harder EU "authorities" seek to suppress it.
It's probably already too late for many European elected officials to avoid the wrath and subsequent punishments once more Nationalist governments are put in place and if you take a look at these abuses, you'll better understand why.
Multiculturalism has pretty much crashed upon the shores of Sharia.
If anything, Europe and much of the rest of the West have proven that while you CAN merge people of different ethnicities, so long as they hold the same common core beliefs (ie. share a common moral code, etc.) you CANNOT merge people who do not...and Sharia's Medieval moral code is not merely irreconcilable with that of the West's, they are absolutely antithetical to each other.
That was an obvious problem that the "multiculturalists" were far too late in recognizing.
That's why things are getting very ugly in Europe right now...and will almost certainly get uglier.
