Most atheists are not overly concerned with what other people believe, and mostly just want to be left alone without having someone try to shove religion down their throat. As an atheist I’ve never had a problem with most religious folks, other than a few truly offensive ones, and never felt any particular desire to try to talk other people out of their faith. Unlike a lot of people on this forum, I don’t lump all religious people in with the relatively few who are truly aggressive or offensive. Not that we get much respect from a lot of those people, who would rather judge people by what they claim to believe than by their actions.
Honestly, I’ve never understood why so many Christians consider atheism to be their ultimate antagonist. From a Christian standpoint, there are much, much worse things you can do than simply not believe in God. I know the First Commandment and all, but I personally have a hard time judging a person’s moral character based simply on whether he or she believes XYZ exists. Belief isn’t something you can just voluntarily switch on and off. It’s not a decision you can make as easily as choosing whether to kill, steal, etc. Yes, an atheistic worldview is going to have a harder time accounting for absolute morality ON PAPER, but I don’t see the average atheist running around looting, killing and living in amoral chaos, either.
Just as atheists shouldn’t judge all of religion based on what the loudest morons say, I think theists should be careful about mistaking atheism for the militant, dogmatic anti-theism paraded by its proponents as “atheism.” Normal atheists don’t need the entire world to agree with them in order to feel good about themselves, so naturally they’re not going to have a very overstated presence.
