I'll be brief. In some old posts on this blog, I wrote words to the effect that Dennis Prager, a right-wing Jewish commentator, was "really" Christian or secretly "wished to be Christian", due to the overlap of his beliefs with right-wing Christian precepts.
This was wrong. I disagree with Prager on nearly every issue, including on what it means to be Jewish and the best articulations of Jewish value. Nonetheless, it is wrong to tell a Jew -- any Jew -- that they are any less of a Jew because of political or social disagreement. Jews are Jews are Jews -- including the Jews I or Prager really, really dislike. As these sorts of attacks on Jews for not "really" being Jewish become more common (and, in particular, seep into the mainstream where even non-Jews feel comfortable challenging the Jewish identities of Jews they dislike), it is especially important to practice what one preaches.
I've endeavored to delete these comments from my archives; it's possible I've missed some. Again, the practice of denying the authentic Jewishness of Jews one dislikes is wrong, full stop, and I was wrong to do it to Prager.
