I think those are seriously overwrought responses. What happened in 1938 was State-sponsored and we are nowhere close to that in this country. We were not even close to it then.
BUT. What we seem to be close to is responding overmuch to political exhortation based on fear. That I find disturbing because it is operating on the right and the left. And the fear is driving us apart from each other and preventing us from simply communicating. In an age where the technology of communication has never been more fluid and accessible. A few short years ago we were predicting that the use of the internet would get diversity of politics into China, would free North Africa from religious dogma, and see the Russians into real Democracy for the first time since a few months in 1917 and again in the 1990s.

Krystallnacht was a product of long-held prejudices 'weaponized' by a violent party which came to power with no intensions of adhering to existing rules of law. They became the willing slaves of a single person and followed a logic which brought themselves and the surrounding world to grief. As I wrote above, I think we've learned a few things since then, I hope we've learned ENOUGH things and retained them through the generations since who have lived without that extreme level of fear and violence. There is plenty of evidence out there that maybe we haven't.

Which is why Krystallnacht is worth remembering.
