Then an atheist actually has no faith that there is no God, and therefore has total commitment to the idea there is God? That can't be what it means either. Without faith that you are right, you can't actually believe in your perspective as being correct, so therefore, by what your saying, an atheist cannot believe that they are correct in saying "there is no God". That makes no sense, just because you say atheists don't believe that their right doesn't mean it's so.
