Curious, aren't these the same groups that insist they are the direct descendents of Egyptian rulers? And if so, they owe the Jews reparations and a few centuries of interest(By their own thinking). So, I vote the Jews get together and sue these idiots for a few Trillion/Quadrillion?
Have you heard of the "Exodus lawsuit" wherein the Egyptians are using the Torah as their "evidence" to sue Jews for property they took when they left Egypt?
