My Aunt referred to me as a heathen because?

I questioned her faith. Yet every point I made about her religion was valid. Her best comeback was that the only thing for certain about the Bible is that there is a god. Was that right since I have conflict with the religion I was brought up in. I.E. A bunch of hypocrites. Not saying that there is no use for religion only people should study a religion objectively like they are learning principles and not putting so much focus on a deity and going around saying "Praise the Lord" all the time.
