As Campus Watch noted at the time, one of them, University of Southern California professor Sherman Jackson is on record advocating the implementation of Sharia (Islamic) law in America. Others, including former Georgetown U. adjunct Dalia Mogahed and Zaytuna College (an Islamic school in Berkeley, CA) founders Hamza Yusuf, Zaid Shakir, and Hatem Bazian (of UC Berkeley), have acted as apologists for Sharia and Islamic terrorism, while advocating an anti-Western, anti-Israel agenda that employs charges of "Islamophobia" to silence legitimate criticism. The primary organizations constituting the Islamist lobby in the U.S. (CAIR, ISNA, MAS, etc.) also endorsed the statement.
As with the 2014 open letter drafted by Islamic scholars that denounced ISIS while remaining ambiguous on crucial theological points, we have to ask, can such a statement be considered sincere if its signatories are Islamists?
