I realize you were just doing your troll thing, but you accidently asked a relevant question so I will answer for people that might really care.
Christians can discuss better islam better than atheists for dozens of reasons, two of the biggest: Muslims convert to Christianity is large numbers, depending on the country some in secret because of the danger. They know the ins and out of both religions. Another big one is the pedophile mohammed was illiterate. Christian slaves wrote down what the pedophile asked them to. Being familiar with Christian doctrine they quickly realized he was plagiarizing portions and making small changes. When they called him out on it, he had them murdered and got different slaves to write down his BS.
Atheists without at least a baseline understanding of both religions has about as much chance at understanding them as you do, which is none.
Remember it was obama that wanted his own army of nazi brown shirts. He must of realized the US Army would never follow him. "We cannot continue to rely on our military in order to achieve the national security objectives that we've set. We've got to have a civilian national security force that's just as powerful, just as strong, just as well-funded."
Good meme, atheists attempting to discuss religion only exposes their ignorance of the subject. Years of attacking Christians robbed any shred of credibility on the subject. Still, I always laugh when they try the "I read the Bible, but.."
