It's hard to find a more formidable debater in the Islam vs. Christianity space than Sam Shamoun. He's probably the quickest on his feet to refute, with instant recall of a photographic memory of the Bible, the Koran, the hadiths and of Arabic scholars. Some describe him as the Ben Shapiro of Islam/Christian circles.
Sam debates live on YouTube. He never gets disconcerted, but his temper flares. "I have a Middle Eastern temper," he says. On a recent live debate, he addressed one interlocutor while others were threatening his life. "Tell your fellow jihadis to put their knives away, and answer the question," he snapped. It seems his use of invective shows he'll not be intimidated by the would-be killers who hate him.
