Adamant, outspoken atheists don't want to see the proof that atheism is essentially, non existent. They have their religion. They have their cult. They like it that way. They won't listen even if they watch your video completely.

There are only two things that take a person away from believing his cult. The are, great joy, or great pain. If you can make an atheist so happy that he forgets about atheism, you might have a chance. Or you can beat him into subjection, and then he might realize the truth after a while. But you'll never convince him from a video if he doesn't want to be convinced.
