In his 1982 book Theft of a Nation, William Baker openly called for the dismantling of the “Zionist State.” In a 1983 speech to the Christian Patriot Defense League in Missouri, Baker referred to the Reverend Jerry Falwell as “Jerry Jewry” (for his friendliness to Jews), and expressed his contempt for the “pushy, belligerent American Jews” of New York City. Baker’s 1998 book, More in Common Than You Think, claims to map “the common ground between Islam and Christianity” and was promoted by the Islamic Society of North America. Islam expert Stephen Schwartz described the book as being “intended to bring together fringe Christians and extremist Muslims.”

In his October 2003 address to the University of Pennsylvania's MSA, Baker said, “Terror, murder -- that’s not what Islam teaches.… It wasn’t Muslims crashing into the World Trade Center; it was haters and extremists.” In an obvious reference to Jews, he said: “Non-Christians and non-Muslims are fomenting hatred for political purposes.” Moreover, Baker condemned pro-Israel Christian preachers like Jerry Falwell, Pat Robertson, and Franklin Graham for having criticized Muslims and the prophet Muhammad. And he referred to the Temple Mount as “the third holiest site in Islam” -- entirely omitting any mention of its Jewish importance.
