I'm not sure how one goes about proving a negative. How does one prove something doesn't exist?

I can't show you God doesn't exist any more than I can show demons don't exist. I do know, using my senses, and with verification by others in the room, that neither God nor demons are in the room with me.

And you can't prove God or demons exist using your senses. You need faith to believe a God is real because you have no objective sensory information that supports your contention. You do not need faith to think God doesn't exist.

Which takes me to respecting each other's "beliefs."

Not all fundamentalism is the same. Inherent in Christianity is the admonition to spread the faith. No such requirement is in atheism.

Atheists may argue their position regarding God, but they don't send out missionaries to spread the "Truth," or the "Good News." They don't put flyers in your mailbox, they don't reward you with eternal life, nor do they condemn you to hell. Unlike Fundamentalist Christians, Fundamentalist atheists don't try to bribe you with a reward, and at the same time threaten you with a punishment. That sort of behavior is nothing less than gangster extortion.

Frankly, atheists don't give a damn what you believe.

No war has ever been instigated for, nor fought over, atheism.

Atheists have not hunted down witches, much less burned them at a stake. Nobody has used atheism as an excuse to limit the rights of others.

Atheists don't demand that the government fund its schools or "Faith-Based" works. I know of no instance of mandated meeting attendance, or requirement to profess atheism, as a condition to receive services or support.

It seems that the difference between a fundamentalist atheist, and a fundamentalist Christian, is the Christian needs the constant compliance of others to justify their faith. I have never met an atheist who gives a damn if someone else is an atheist.

As an atheist, I acknowledge your right to your faith. But that doesn't mean I respect your faith or support your attempts to impose your faith on others.

Fundamentalism is a position. What you do from your position is quite another thing.
