Why does religious discrimination become a form of racism?
Jews are an ethnicity first and a religion second. You only have to look at their religion to know that it is ethnocentric. The only way to be a Jew is to be born of a Jewish mother, or to convert. Converting is a difficult process, and then even some Jews do not recognize a convert as a true Jew. You are confused because it is intentionally confusing. Jews often hide behind being a different faith, but they are in fact an ethnicity. There are many Jews who are not religious but still identify themselves as Jews because they were born of a Jewish mother.
