Yeah, I suppose one would just be a bigot, not much of a step up the social evolutionary ladder though.
How does that work with Jews? I mean, it can be an ethnicity, but it can also merely be a religious choice. So disparaging Judaism is not racist, right? It isn't even anti-Semitic since one could feel quite differently about their secular friends of Jewish extraction.
I recall a friend telling me that his Mom wouldn't let them tell "Pollack" jokes back when those were making the rounds, because ethnicity wasn't something that anyone had any control over.
However, as a UT grad, the jokes were perfectly fine with her if they changed "Pollack," to "Aggie," since people made a conscious choice to be Aggies.
Religions are systems of ideas that result in patterns of behavior. At some point, people choose to adopt religious ideas and patterns of behavior and become accountable for both.
You don't really believe that religious beliefs or the behaviors that they inspire in some of their adherents renders them exempt from criticism or scrutiny, you?
In the case of Judaism, however, ethnicity is often the basis for self-identification, not practicing religious belief.
