Theist religion is based on where your born. If you're born in America, you'll more than likely be Christian. However were you to be born in any number of other countries, you would more than likely NOT hold those same beliefs. Therefore, theist religion is often held, becuase people just go along with what their parents teach them as a child. Remember: religion is easy when every answer to every logical question is a one word answer, "Faith". Faith to me means "I don't need to know because that's what God tells me."
