As a Christian, I find it tacky for a believer to sort of "crash the party" of this topic and either bash atheists/agnostics or try to evangelize to them, judge them, or thrust their beliefs in people's faces here. It won't work, mostly because this isn't the time or place for it. Have respect for other people's beliefs or non-belief, and don't presume or presuppose why they think like they do. Sometimes not coming across as a self-righteous jerk (not saying that anyone is, just that people may take things that way) is the best way to get someone to see your point of view.
I've visited this thread in order to be able to view U2, their songs, etc. through the lenses/ears of non-believers. Your experiences and thoughts greatly interest me.
I love this thread and will go back to just being a voyeur.
