Now, a few caveats. The GSS has a good rep, but frankly, I'm a little suspicious because the stats for Jews who "oppose" or "strongly oppose" marriage to generic whites is zero. That sets of the alarm. Moreover, I think it's wise to consider opinion studies in some context and not quote them as definite, concrete markers of reality.
That said, that Jewish disapproval of interracial marriage with blacks would be higher than the reverse, doesn't really surprise. Religion is likely a factor--but so is being white. I don't think Jews or anyone else is immune to history.
What would really be interesting, and much fairer, would be to compare the Jewish numbers, not with blacks, but with other whites. I think that would tell us a lot more. And then, as it is with these sorts of things, not much at all.
