Not a member of World Without Nazism (RfC) 

Dovid Katz spoke at a conference of World Without Nazism, and he was subsequently wrongly reported by Russia Today as being a member of World Without Nazism. He has never been a member of World Without Nazism, opposed their stance on Soviet crimes when speaking at the conference, and Russia Today is the only source of his "membership". This citation is now being used as an attempt to defame him on his Wikipedia page. An edit war is starting and I would appreciate comment. As far as I can see, one source is not sufficient for adding a controversial and potentially defaming "fact" to a biography of a living person.
