I had this discussion with a professed atheist, Sevy, on my Facebook page recently after he responded to my blog post Circular Reasoning?. A few other Christians joined in the discussion and made some good contributions.
Notice that he wrote Brian instead of Brain - but I guessed he meant brain rather than the Life of Brian.
Note - I watched a few minutes of the Perfect Double Standard video and it's the usual offensive vile and absurd nonsense that DarkMatter2525 posts.
Towards the end Clifford said that Sevy needed to go off and study logic, but I don't think that a lack of understanding of logic is the main problem - the problem is that without God there is no solid basis for absolute and unchanging laws of logic and so no real reason why illogical or contradictory things would be absolutely impossible. This illustration puts it well:
At this point Sevy blocked our page and went off to moan and groan to his atheist friends on an atheist page he is part of. He tagged me in, so I got screenshots of him venting his frustration.
