Why don't christians have to defend themselves?

Tell some one that you don't believe in god and chances are you will be asked to defend your point of view. I will bet my left lung that if jehovah's witnesses come to your door and you tell them you don't believe in god they will demand to know why you think the way you do. This is when I demand to know why they think they can come to MY door and questions MY beliefs. Then I tell them they should be thankful that I'm not a Satanist. While they're trying to come up with some biblical quote to show me how wrong I am, I ask them how fast they think can back their car down the driveway.

Unlike these rude, presumptuous people, an atheist will never show up uninvited at your door to try to make you believe what they believe. We know that in order to "make" someone believe something you have to start at birth, and brainwash them daily (or at least once a week) using fear and wild tales with no factual basis. That's just not how we roll.

It is only when people are allowed to think and question and search for the logical truth that an atheist is born.
