Laurence Auster was actually born Jewish (he converted to Episcopalianism): he is a cousin of the novelist Paul Auster.

Actually, Wikipedia claims he has criticized paleocons like Pate Pukecannon for antisemitism in the past…

Is there no chance at all that Auster sent this as “an example of the antisemitic tripe peddled by David POS Duke”?

There are unfortunately enough Jewish antisemites out there that we should be careful not to invent new ones.
