Hmmm...a serious question. "moral equivalence between the modern day persecution of Jews and the modern day persecution of Christians of any flavor" -- now what Hitler did was hate Jews or even Jewish converts or even if your great-grandfather was a Jew. Hitler was a racist as he hated the Jews due to their race.
Now if someone used the terms Jews in the religious sense and said some of the things ZC said here against Catholics, would it be anti-Semitic?
Many religions disagree with the beliefs of the Jews much like they disagree with one another. That is to be expected on "open" Religion Forum threads.
Atheists, for instance, agree with "none of the above."
Anti-Semitism is not simply a theological disagreement.
