It's a smokescreen/ race card. Somebody is calling you out and you can't address the points they are talking about you call them a bigot (in this case an anti-semite) and you make not so veiled threats to them.
That's exactly what it is. He can't address the accusations because he knows he has no credibility, so he comes up with something like this.
And good luck to him if he's serious. I worked in the Jewish community for 25 years. There's not a Christian in this world who's more respectful to Judaism (and more pro-Israel) than I am.
I'm Catholic. Our religion (and all forms of Christianity, for that matter) sprang from Judaism. Jesus was a Jew. Without Judaism, there's no Christianity. But I'm going off topic now, so....
