DO you know the reasons that you're committed to your faith? do you truly not need an atheist to tell you why you believe what you believe?
guess what. the only reason you believe what you believe (about your faith), and know what you know, is because someone else, or some other factor/stimulus in your environment told you why/how to believe what you believe. You convey your inability to be openminded by dismissing an idea that your own life/beliefs prove to be true.
