The more crescendo the hysteria goes, the less likely this will end well.
I think the main issue is that most people have their viewpoint, stand their ground and don't even listen to each other.
One the one side, you have people who take offense. On the other side, you have people who deem it ridiculous and who say that they are overreacting.
But it's not very difficult to take the offense away.
For children, it won't matter if "Zwarte Piet" is an asian or white guy or woman. They won't care if Sinterklaas is suddenly a black guy. Sinterklaas usually has more than one servant. It's perfectly possible to keep the fairy tale intact and have 4 Pieten of different skin coulour and/or why not a black or an asian Sinterklaas.
Even if you find it a bit silly that people are offended, one must admit that it is very easy to keep the tradition, but in a less offensive package.
A small compromise and everybody is happy again.
Ridiculous or overreaction or not, it's not that hard to find a decent solution that satisfies everybody.
People often are way too busy with their own rightheousness instead of just proposing a satisfying compromise.
Instead of looking for arguments to prove one is right, one should better use his creative juices to find a solution for the issue. And in this case, a solution is very easily found.
