Great question. We need a brief response to it.
Something like "your definition of atheism is a religious one - we atheists don't accept religious definitiions"
Here's one that's comes from believers and right-wing atheists:
"As an atheist, haven't you just replaced god and religion with State and government?"
My previous reply apparently got lost in the system somewhere so I'm repeating:
State and govt are human-made and can be abolished by humans (usually via votes sometimes revolutions). God and religion are not.
There is also the tendency for religious folks to define atheists as 'anti-religious' when we can more simply define ourselves as 'without religion'. Not that I can't find reasons to criticize the things people have done in the name of Jesus/Allah/God/Yayweh/etc, etc, fill in the blank with supernatural belief system. But not every atheist is a 'militant atheist', correct?
Atheists can see why a belief system may rationalize individual behavior, provide a sense of belonging/comfort and conclude that it has good and bad components, right?
I have trouble countering the argument that religion keeps people from fearing death.... countering that (in my opinion) false sense of security that heaven exists in the afterlife. Who am I to call a person silly or irrational for a belief that keeps them from suffering from existential crisis?
Can I just point out that it's a little arrogant to think that you can speak for atheists as a whole and answer questions as if atheism was some kind of monolothic entity?
After spelling monolithic wrong I don't think I can take being asked serious questions.
But seriously, I was trying to make a serious point: atheists have vastly different philosophical, political, social and scientific perspectives so the idea that someone (or even a group of people) can make an "Atheist FAQ" is a quite weird one. Just me adding my opinion wouldn't make it that much different.
Whenever I see people talk about what "we atheists" think, it makes me a little nervous. It makes me feel like I signed up to a clique where others get to speak in my name.
I guess what I'm getting at is that right at the top of the list it should point out that these answers are by no means gospel, and that nothing guarantees that all atheists (or even a majority of atheists) adhere to it. It's just a collection of opinions to give theists an idea how these arguments might be answered by your average atheist.
And I don't mean this in a disrespectful way at all.
Just saw that at PZ Myer's blog:
Ah, "stumper" questions. My favorites of all time:
5. "How did males and females evolve separately? Hmmm?"
4. "So what happened before the big bang, hmmm?"
3. "So why is the Bible's order of species creation in Genesis correct, hmmm?"
2. "Who made you, then, hmmm?" --moment of sadness: this one came from my own mother.
1. "Then how does this chair, which weighs 10 pounds, support a pastor like me, who weighs 300?" --I offered to answer him, because I know the physics of that, and he said, "No, that's not the point..."
Of course. Getting an answer never is the point; the point is that they don't really want to know.
