A Former Jew explains in 1961 that Jesus wasn't a Jew, if he was a Jew there's not a Jew in the world today.

The Jews - I call them Jews to you, because they are known as Jews. I don’t call them Jews. I refer to them as so-called Jews, because I know what they are. If Jesus was a Jew, there isn’t a Jew in the world today, and if those people are Jews, certainly our Lord and Savior was not one of them, and I can prove that.

He also explains that the term antisemite is meaningless because jews were not semites.

Now what happened? The eastern European Jews, who form 92 per cent of the world’s population of those people who call themselves Jews, were originally Khazars.
They were a warlike tribe that lived deep in the heart of Asia. And they were so warlike that even the Asiatics drove them out of Asia into eastern Europe - and to reduce this so you don’t get too confused about the history of Eastern Europe - they set up this big Khazar kingdom: 800,000 square miles. Only, there was no Russia, there were no other countries, and the Khazar kingdom was the biggest country in all Europe - so big and so powerful that when the other monarchs wanted to go to war, the Khazars would lend them 40,000 soldiers. That’s how big and powerful they were.
Now, they were phallic worshippers, which is filthy. I don’t want to go into the details of that now. It was their religion the way it was the religion of many other Pagans or Barbarians elsewhere in the world.
Now, the [Khazar] king became so disgusted with the degeneracy of his kingdom that he decided to adopt a so-called monotheistic faith - either Christianity, Islam - the Moslem faith - or what is known today as Judaism - really Talmudism. So, like spinning a top and calling out "eeny, meeny, miney, moe,"he picked out so-called Judaism. And that became the state religion.
He sent down to the Talmudic schools of Pumbedita and Sura and brought up thousands of these rabbis with their teachings, and opened up synagogues and schools in his kingdom of 800,000 people - 800,000 thousand square miles - and maybe ten to twenty million people; and they became what we call Jews. There wasn’t one of them that had an ancestor that ever put a toe in the Holy Land, not only in Old Testament history, but back to the beginning of time. Not one of them!And yet they come to the Christians and they ask us to support their armed insurrection in Palestine by saying:
"Well, you want to certainly help repatriate God’s chosen people to their Promised Land, their ancestral homeland,It’s your Christian duty. We gave you one of our boys as your Lord and Savior. You now go to church on Sunday, and kneel and you worship a Jew, and we’re Jews."
Well, they were pagan Khazars who were converted just the same as the Irish [were converted]. And it’s just as ridiculous to call them "people of the Holy Land," as it would be ... there are 54 million Chinese Moslems. Fifty four million! And, Mohammed only died in 620 A. D. , so in that time, 54 million Chinese have accepted Islam as their religious belief.
Now imagine, in China, 2,000 miles away from Arabia, where the city of Mecca is located, where Mohammed was born ... imagine if the 54 million Chinese called themselves “Arabs.” Imagine! Why, you’d say they’re lunatics. Anyone who believes that those 54 million Chinese are Arabs must be crazy. All they did was adopt as a religious faith; a belief that had its origin in Mecca, in Arabia.
The same as the Irish. When the Irish became Christians, nobody dumped them in the ocean and imported from the Holy Land a new crop of inhabitants that were Christians. They weren’t different people. They were the same people, but they had accepted Christianity as a religious faith.
Now, these Pagans, these Asiatics, these Turko-Finns ... they were a Mongoloid race who were forced out of Asia into eastern Europe. They likewise, because their king took the faith - Talmudic faith - they had no choice. Just the same as in Spain: If the king was Catholic, everybody had to be a Catholic. If not, you had to get out of Spain. So everybody - they lived on the land just like the trees and the bushes; a human being belonged to the land under their feudal system - so they [Khazars] all became what we call today, Jews!
Now imagine how silly it was for the Christians ... for the great Christian countries of the world to say, "We’re going to use our power, our prestige to repatriate God’s chosen people to their ancestral homeland, their Promised Land."
Now, could there be a bigger lie than that?
