I think Anti Semitism from the right is more immideately dangerous because it is more violent.
I already posted a response to this, which I stand by, but upon further reflection I've kind of rethought my answer.
Let me start by rephrasing my original question. Which is more dangerous, when a small group of bigots get together, get drunk and go out and push over some gravestones? Or when a mainstream, well organized and well funded group that has thousands of members attacks the very notion of a Jewish homeland, arguing that such a homeland is a danger to "World Peace and Security"?
I'm not defending the idiot bigots that go and vandalize property or phone in phony bomb threats, assuming for the sake of argument that's what it turns out to be. They should be tracked down, charged, and prosecuted to the fullest extent of the law.
But I would argue that no matter how bad the first group is, or how much damage they cause, they are less of an existential threat to the Jewish people than a group who chants "Palestine will be (
Juden)-free, from the river to the sea!" at their rallies and argues against the very existence of a Jewish homeland.
Now, if the alt-right (again, assuming for the sake of argument that's who it was) succeeds in replacing the traditional conservative right and actually gets organized and funded it could turn out to be just as bad as the BDS movement, but for right now that's not the case.
