Hmm... I'm not actually sure I saw that Sharpton got "mutilated" exactly. Although, I find debates of this nature fairly impossible. Since debates rely on logic, generally speaking, a debate on religion can't be won by people who use "faith" instead of logic as their discussion base. There's little point debating someone who doesn't accept the same debate framework and foundation of science, fact and logic.
