Why do people continue to try and convince others that those in Israel aren't really Jewish, but Khazar?

If those millions in Israel are supposed to be Khazar, then where do they think, people who would be the real Jews, are located?

Or do they think that the LORD had all of the real Jews killed back in 70 AD & 135 AD?

Do they believe that the Khazars managed to deceive all those antisemites into thinking that they hated Jews, when they weren't even Jews, only Khazars?

Do they believe that the Khazars managed to deceive the nations of the world to vote in the UN in 1948?   All those nations didn't know?

Is that why there are holocaust deniers, because they think that there were not 6 million Jews killed, but only 6 million Khazars killed?

Do they believe that the Khazars managed to deceive everyone by bringing back the Hebrew language, and the shekel?

Do they believe that the Khazars managed to deceive people about black Khazars from Ethiopia? Or Khazars from ancient settlements in India and Yemen?

Do they believe that someone needs soon to warns Jesus to not return to Jerusalem, since there won't be Jews there, but only Khazars?
