:::Don't quote me out of context, LeContexte. It is not my argument that opinion pieces  such as the Jewish Chronicle article and this blog entry which were both added to the article  are questionable sources. It is Wiki policy, and for good reason. From WP:QS, with the salient points bolded: 
 :::Questionable sources are those with a poor reputation for fact-checking. Questionable sources include websites and publications that rely heavily on rumors and personal opinions, are promotional in nature, or express views that are widely acknowledged as extremist or pseudoscience. Because of this, they can be treated similarly to the way self-published sources are treated. Questionable sources should only be used as sources about themselves as described below. Articles about such sources should not repeat any contentious claims the source has made about third parties, unless those claims have also been published by reliable sources.
