By that logic, we can't conclude that anti-Semites are racist until we've resolved the scholarly debate as to whether the Jews constitute a "race" of their own.

By that logic, we can't conclude that anti-Semites are racist until we've resolved the scholarly debate as to whether the Jews constitute a "race" of their own. I'm not saying that Jews shouldn't be regarded as a race. I'm saying that your moral reactions shouldn't be contingent on morally irrelevant descriptive features such as whether the group being discriminated against constitute a race or nation or ethnicity. It's even possible for people to discriminate against people from a state or city. Should we wait for a special word like "statist" and "citist" to be coined before suddenly discovering that this is wrong? And don't tell me: "but the reason we want to treat these people differently is because of their moral characteristics, it's not that we are biased against them". Go read Mein Kampt and tell me this isn't exactly the rationale for anti-Semitism stated in it.
