Following the ferocious response by Alex Stein and Did Remez to my previous post, I'm issuing a correction.
The lie about Israel gearing up to deport tens of thousands of Palestinians, repulsive as it is, probably isn't extreme enough to justify the title I gave it, "blood libel". A blood libel is when enemies of the Jews propagate a story about how Jews are murdering innocents. While there is no dearth of such stories in the reportage on Israel, this particular lie is not that serious. Its propagators are reporting on an Israeli policy which doesn't exist, but they're not saying Jews are murdering anyone.
So, here's my retraction of that terminology.
As for placing some of Israel's own radicals in the camp of its enemies, that unfortunately is something they have done. I'm merely reporting on it, though with great reluctance and some real pain.
