Mort Klein a racist?

This, from the most recent issue of the Forward regarding a group of Neturei Karta joining the ZOA-sponsored anti-disengagement demonstration outside the United Nations this past Tuesday:

Despite the crowd's discontentment with Sharon and the Israeli government, protesters reacted angrily to the sudden appearance of a small band of anti-Zionist ultra-Orthodox Jews. As the men, members of the Neturei Karta sect, crossed the street and approached the gathering, the crowd booed loudly.

"This is the most lunatic face of Judaism on the face of the earth," ZOA's Klein said from the stage. "They won't even marry people outside of their sect — that's why they have so many diseases."

Excuse me? Isn't that what the Nazis said about Jews sixty years ago?

I think it's completely unacceptable for a Jew, let alone the president of a pro-Israel/Jewish organization, to utter anything of the sort, especially at a rally. This is simply outrageous, please call the ZOA at (212) 481-1500 and express your opinion.
