Their philosophy is a little warped.

Author and retired neurosurgeon Dr. Ben Carson said Thursday that the Islamic State of Iraq and Syria (ISIS) is willing to die for what they believe in, but they have “the wrong philosophy.”

“We’ve got ISIS. They’ve got the wrong philosophy, but they’re willing to die for what they believe, while we are busily giving away every belief and every value for the sake of political correctness. We have to change that,” Carson said at the Republican National Committee’s winter meeting.
