Another problem is that the rise of social media has given bigots the world over a large enough echo chamber that they feel supported, even though their direct environment does not support them.

This is not something I have seen yet but that could be luck of the draw.
> And in a recent election the extreme right won more than a third of the votes.
Indeed they did. But: that percentage wasn't all that different in previous years overall, if you add up the various splinter groups. They were just less vocal and they did not have international ties the way they do today. This is an extremely dangerous development.

I believe you.

Yes, it is like a cyclic thing that is driven by the loss of lessons learned from the past. NL is in a particularly difficult spot here with our history in Surinam, former dutch Indonesia and the slave trade. We've done some very ugly things and a lot of that required de-humanization of other people to a degree that it still stains our culture in a very significant way.
Lots and lots of crimes were committed, lots of mistakes were made. It will take many generations to come to some kind of new equilibrium. It certainly won't happen in my lifetime, and probably not in my kids' lifetimes either.
