Kyle seems to hail from Jewish ethnicity with his surname and separatist-like Jewish camp's approval of him being a scout there. Not to mention Cartman's dream, but that's technically not a real thing. So if Eric wanted to, he could be mocking the Jewish race itself more than the just the followers of the religion.

And since Cartman's name shows really no strong sign of Hebrew heritage, it wouldn't be really contradictive of him to tease the race in that sense. If that even makes sense.
