Funny you mention Amsterdam, where a large portion of the original inhabitants moved to Almere which accidentally happens to be one of the hotspots of the PVV. People tend to vote with their feet if nobody listens to them. Same happened in Suriname.
Not that I don't agree to the fact that Amsterdam still is one of the coolest places in the world also because of all the different people living there together. But sometimes you could acknowledge that not everybody that comes to Amsterdam comes with the idea to make it a better place together. Wouldn't you agree a true citizen of Amsterdam would be tolerant toward people of the same sex walking hand in hand?
But the famous red light district has been closed for a large part, new ridiculous rules for coffeeshops, ban on magic mushrooms (together with a rush of half or non true news items that seemed a throwback to the time the US wanted to ban marijuana in the 1920's and needed popular support for that).
It just goes on and on and on and all measures really only seem to affect people's liberties never the true criminals.
