Your statement brings to mind the story of the doubting Thomas, who did not belive that Jesus had been resurrected until Jesus Himself showed him His wounds.
Believe or don't believe in any sort of an afterlife as you wish. If you don't believe in an afterlife, at least have the decency not to try to convert those of us who DO believe in an afterlife over to your view.
IMO, the point of the article is not so much that some of those who follow Judaeism don't believe in an afterlife.
The article infers that NO Jew believes in an afterlife. The article, therefore, seems meant to incite hatred toward the Jewish population in general, thereby bringing the anti-"zionist", Jew hating crowds out of the woodwork. In that, the article seems to have succeeded.
I don't understand why someone who believes in an afterlife would possibly hate someone else (Jew or otherwise) who does not believe in an afterlife? The believer might feel an emotion of pity for the unbeliever, or the believer might feel pride in their belief compared with the unbeliever, or the believer might feel ambition to change the unbeliever's view. But hate?
