Yeah, sooner or later, people are going to call christians and people with beliefs idiots.
I don't think that Christians and other people of religion are idiots. My own mother believes in Ahura Mazda, the Zoroastrian term for God. I am by blood a Zoroastrian, and I had my navjot (religious ceremony where I turn into an adult, like a barmitzvah). I memorized prayers in a language I can't even speak, and I trusted in them for a long time. But then I began to think about things, and learn things. God seemed less and less likely, and so I changed my views on the Universe. Zoroastrianism (aka Zarathustrianism) has very few followers left in the world, and I want to preserve it for my children. I will let them choose their own truths, so that this ancient religion can be preserved, even if I do not believe in it.
Sorry about rambling there guys, I just had this on my mind.
