But as all seemingly extremists becoming prime ministers, he'll eventually learn to see a bit more of the bigger picture and cool down if he gets in office.

This is a very scared, very scary person who is pushing every emotional button available with his policies and rhetoric who has the backing of a much too large segment of the country already. If you had told me 25 years ago that this would happen in NL I would not have believed you but I'm witnessing it. This whole thing started with the murder of a guy called Pim Fortuyn, the previous populist (who at least made some sense some of the time), he would have done some damage but not enough to seriously threaten the country. The segment woken up by the voice of Fortuyn was then handily co-opted by Wilders, who is now in an excellent position to put his play-book into action. It's super scary to watch friends and even relatives succumb to this idiots words and to hear his words being echoed by people dear to you.
It's like watching a re-run of Germany, ca. 1935, and then too people were saying 'Oh, it won't be that bad, he's just going to wake up when he actually has power' and we all know how that one ended.
Again, fortunately, NL is a crappy little country, but don't forget that Hitler came from Austria, not from Germany to begin with, who knows what his plans are. There is a large body of similar minded people in Belgium, and a much larger one still in France led by one Marine Le Pen. You can bet they're planning some sort of collaboration (too early to call it an anschluss) once they have managed to capture some power.
It's like watching the periscope of a submarine moving through a flotilla of merchant boats.
