Sorry, we don't live in a should-universe, either. If your goal is to influence a religious person's perception of his/her faith, you do what it takes to get through, not complain that the other party is not playing by some real or imaginary rules. But hey, feel free to keep talking about logic, rationalism and respect. That's what two-boxers do.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
