[Matthew Shea]

Natsu, in my experience, atheism comes in many flavors. There are the "God does NOT exist" atheists, who think believers are inherently foolish and there are the "I see no evidence of God" atheists, who don't necessarily shut their minds to a supernatural power, but don't anticipate that anyone will be able to convince them. The latter flavor of atheism tends to leave the doors of belief cracked open just enough to keep a balanced view of the world, while the former does not.

To add onto what Groundless said, I completely agree. None of us, myself included, have it all figured out. That's what makes an open mind so important. You have to be open to the fact that you may be wrong and you have to be open to changing beliefs in the face of clear evidence that something better awaits. That being said, you can't shove beliefs down people's throat, either. You can certainly have a good, honest debate, but in that case, conversions rarely occur. It's usually just an exchange of ideas. To convince people who are open to being convinced, you really have to show them the better way and approach them with love and respect for what they've been taught and what they now believe.
