Appears to be misinterpreted from The Talmud. Since no one reads the source material, then it's easy for distorted information to get perpetuated. Or maybe some people are deliberately putting out distortions to cause chaos. https://www.quora.com/Is-it-true-that-the-Talmud-contains-racist-and-genocidal-rhetoric-towards-gentiles The Talmud is a book of debates; it uses a method similar to the Socratic method. Statements are made, supposedly by one of the rabbis engaged in the debate that is being reported, in order for others to rebut those statements. Many of the statements that are made initially (often phrased as a question, but sometimes as a statement) are made solely for the purpose of opening the debate before showing that something is incorrect, and why it is incorrect. So there are statements that say that non-Jews are “lesser beings”, only to be rebutted, using proof from the Torah and the Mishnah. If you can read and understand the entire debate, the conclusion is that non-Jews have the same value as human beings that Jews have, and that we must treat them fairly, just as we must treat our fellow Jews fairly.
