 One response to this objection is that the move from \(\Pr(T) \le 0.5\) to \(\Pr(T) \lt 0.5\) is not insignificant, since it is a move from a situation in which acceptance of theism may not be irrational to one where it is certainly is.  Nevertheless, the objection does bring out an important point, namely, that the argument as it stands says nothing at all about how much below 0.5 the probability of theism is.
