Any action, practice, or belief that reflects the racial worldview—the ideology that humans are divided into separate and exclusive biological entities called “races,” that there is a causal link between inherited physical traits and traits of personality, intellect, morality, and other cultural behavioral features, and that some “races” are innately superior to others.Rabbi Kahane's opposition to Arabs in Israel was not due to any genetic/biological differences that may exist between Arabs and Jews. I remember at least one case of an Arab that converted to Judaism who joined Rabbi Kahane's Kach party. Rabbi Kahane's desire to rid the land of Israel of its Arab dwellers was based on his understanding of Arab national/religious aspirations here, and that they will never live with us in peace and harmony.
Kahanes opponents purposely applied the racist label to him because they lacked the intellectual ability to debate him on the issues that he raised. It is also interesting to note the following from britannica.com:
By the 19th century racism had matured and the idea spread around the world. Racism differs from ethnocentrism in that it is linked to physical and therefore immutable differences among people. Ethnic identity is acquired, and ethnic features are learned forms of behavior. Race, on the other hand, is a form of identity that is perceived as innate and unalterable. In the last half of the 20th century several conflicts around the world were interpreted in racial terms even though their origins were in the ethnic hostilities that have long characterized many human societies (e.g., Arabs and Jews, English and Irish).Rabbi Kahane was a great Jew, towering above the shallow Jewish "leaders" who were unwilling to honestly discuss and face the issues at hand. May his memory be a blessing.
Update: An anonymous commenter to this blog claims that Rabbi Kahane thought and wrote that Arabs are biologically/genetically inferior to Jews. I challenge anybody to bring a source to this outrageous claim!
