"Mr. Maher is correct on the overall effect Islam is having on the world right now," O'Reilly said. "The truth is militant Islam continues to drive worldwide terrorism and have plenty of sanctuaries from which to commit their evil."
"Ben Affleck should well understand that he himself would be beheaded in a heartbeat by these ISIS animals," he continued.
Maher had hosted Affleck and author Sam Harris Friday on HBO's "Real Time With Bill Maher" for a discussion of Islam. Maher stated his belief that Islam doesn't practice liberal principles. Harris agreed and added, "Islam, at the moment, is the motherlode of bad ideas."
Affleck was outraged by their comments.
"It's gross, it's racist," he said.
