I don't see any validity in drawing any conclusions about "jews" in general from anything Foxman said. He speaks for himself, and I suppose one could argue that on some occasions, he speaks for the ADL. But this appears to be something he wrote as an individual and does not constitute the "official" views of the AFL.
There is some value in commenting on it now because he apparently just wrote it. But the only conclusion I draw from what he wrote is that he personally is not someone I'd take seriously in the future. It's a comment on his personal credibility, IMHO. Nothing more, and certainly nothing that would justify any blanket assertions about people of any race or faith.
Well, in fairness, it appears from the context of the article that Foxman published it very recently......
You are correct. He should shut up about this subject. He's said his piece.
