For the most part I agree with you, but I have a small caveat with number seven. If the argument is restructured to "I don't believe in your god for the same reason you don't believe in every other one", it still encompasses the same idea, but is also more or less correct. I do think that it is a stretch to say that theists are 'atheists' to gods other than their own, but I agree with the basic idea that the argument is trying to put forward. Theists dismiss other gods, but generally do not apply the same level of skepticism to their own religion.
