Anti-Semitism as a term is broken because of Israel. Because that country has accused everybody opposing what it does no matter how horrific as somehow representative of a whole race of people.
It is truly nonsensical as well because Arabs are a Semitic people's as well. They are all the descendants of the ancient Phoenicians and others, the carthaginians.
Israel is the most anti-Semitic country in the world, straight up bigotry against Semitic peoples of the arab tribes.
