Jim, we agree that was a pretty disgusting reaction from Dunthorpe, but he's been a  very open outspoken anti-Semite here.
Regarding  Eli Wiesel, he was a remarkable man, outlasted the concentration camps with his mind and morals intact, wrote and taught about peaceful relations, and certainly deserved  his Nobel Prize.  He's spoken out powerfully on any number of world conflicts on behalf of the victims. 
 I like the quotes Karen Meyers used here.
However, there is one side of Wiesel which has bothered many people for years--his refusal to directly speak out about the suffering of the Palestinians at the hands of the expanding state of Israel.  Jim, if you google "Wiesel and the Palestinians" you'll find lots of examples.
What makes this especially upsetting to many people has been precisely his famous quote "Neutrality helps the oppressor, never the victim. "
