Atheists who become theists weren't atheists to begin with. They were angry at god and denounced god. They still believed but were having the religious equivalent to a temper tantrum. When they calm down they stop denouncing God and become good little theists again. This shows by his misunderstanding in thinking all atheists are mad at or hate god. For me to hate you, or even be mad at you, you must exist. Its why people aren't mad at Osiris or Odin, or Zeus. They don't exist. Are you an atheist for being mad at Odin for not having a shorter winter? Nope.
