Most atheists do not think about religion much at all. In fact they probably do not even stop to think of themselves as atheists. They just accept that there really is no God.
Those who do think further about religion are generally accepting of the rights of others to believe what they want to believe, even though there is no evidence for those beliefs. They are occasionally cynical when some evangelisers try to convert them to Christianity.
Answer:
Consider what adults think about the monster under their bed, or Christians think about Tyr and you'll be close to what atheists think about religion. The common thought is that atheists have a hate on for all things holy, that they eat their bowl of warm kittens in the morning and then go out to glower at churches. Not so, we get up, go to work, come home to the wife, kids and dog just like everyone. During almost all of our days the thought of religion, clergy or scripture never crosses our minds. The few show-boating atheists in the news, like the showboating evangelicals, taint people's minds about what atheists are all about.
