Who knew it was legal in Holland to muzzle free speech

Here's a video clip of the dutch putting a politician on trial for being a racist asshole. While I agree that it is base and utterly classless to rail against an millions of people one has never met, I feel like throwing people who do so in jail is wrong. It's important for people to be able to articulate their views, even if they are offensive. But the Dutch justice system doesn't seem to think this way, which is why they suck.
