Anti-semetism. Distraction from follow the money trail
See my earlier post on genetics between arabs and jews. Waves of people criss-crossing the planet. Many jews have traces of Chinese from the silk road and mongol invasions, many were deported by the Ottomans from central europe to far flung parts of the Ottoman empire, and so on. War, drought, economic opportunity have all had an impact. So all this talk of "arabs" and "semitic" is nonsense once the DNA is examined. Ancient Babylon was a tumble dryer of genetics. Ancient Rome spread DNA far and wide, especially England.
We are hopelessly intermixed with DNA. Religion and ideology are just labels to justify what is basically greed and stealing of resources from somebody on the other made up side and artificial differences. There is more variation of genetics within causcasions than as between Africans and causcasions.
The "anti-semitic" thing is mostly a reductionist rhetorical tool / trigger to castigate and marginalize anyone who has a problem with the policies of those who claim to speak for the Israeli people, any more its "anti-American" to peak badly of whatever administration is power (virtually all are finacially corrupt and don't give a toss about the population or the future). Another cheap tool to manipulate and divide.
