I'm going to jump in here, because you're really trivializing the concept of faith with this comparison. Atheists have a position, whether or not they are willing to admit it, but it doesn't take faith to pick a side. Faith isn't what separates the theist from the non-theist--a deist who thinks that the evidence points to the existence of God but refuses to ponder the question further doesn't actually have faith either.
Religious faith, especially Christian faith, is different. It is unreasonable. But so is falling in love; so is walking out the front door. You're stepping off a ledge into the unknown, surrendering control, placing a wager on the possibility that life actually does have meaning.
Agnosticism, on the other hand, is entirely reasonable. It doesn't take much of anything to say you don't know and then slam the door shut on life's most profound questions. I'm not sure when apathy became a virtue, but it doesn't get much easier than not caring.
