Tariq Nasheed creates are nearly fail proof argument. However, no matter how nonsensical the argument is, he places the burden of proof on the person who he's debating. If you can't proof what he says is false, then it must be true; it should be if HE can't prove what he says is true, then it must be false.
He also used all encompassing words, and phrases to further prove his points. If one puts the burden of proof back in Tariq, by not letting him answer a question with a question, ask him for proof of said allegations and not just use all-inclusive phrases, You'll win the debate.
