AWESOME response, KingJ. You never let me down.
I don't know if I mislead you to thinking that I reject the "dumb" aspect because it is impolite. I don't think it's that I reject it because it may hurt someone's feelings, but rather I honestly don't think the discussion itself is dumb. However, a final conclusion to not accepting God can be dumb, without question. Statements like "I don't see him, therefore he doesn't exist." is a dumb conclusion based on a logical fallacy. So it's possible that I am making my case poorly -- a conclusion can be dumb, and so can an argument, but I don't think that means that every time the discussion is had, it will be dumb. I think sometimes reasonable arguments are made, even if there is an even more reasonable rebuttal.
With Christians who find God (as many may find him on different paths), it is still possible for an argument for God's existence to be off-center or poor or even dumb, even though the conclusion is right. "God exists because the universe is so old, it required God to come into existence to take care of it." This is a real argument I've heard, and I would never agree with it because she suggested that the universe is eternal and God is bound in time because he came into existence...but she's still right in knowing that God is real even if it is a childish understanding of God (when I was little, I literally believe God lived in the clouds).
I could be going off track with that one. I hope I'm still making sense (heck, I hope I was making sense from the start).
I'm trying to figure out whether you are right or wrong in saying there is only one dumb statement and it is embedded in their title. I realized we're not discussing whether or not Atheists or right or wrong -- we agree they're wrong. It looks like we're discussing the definition of the word "dumb."
While I think it can be quite often (the discussion I mean), I think it is sometimes instead just misguided. I think it's possible to be misguided and still not dumb at the same time. Although that isn't to say every individual is being misguided -- some are in fact responding in a dumb way.
Dawkins is an interesting character. He isn't the single voice of Atheism, though he is probably the loudest and is the sort of darling of "New Atheism." Opposite Atheist voices, I'd say, would be writers like Scott Aiken and Robert Talisse who do hold strongly to their Atheistic opinions, but are very sympathetic and respectful to theists, even if they don't respect theism itself enough to believe it. But regardless of which color of Atheist we're discussing with, I'm not sure using the Scriptures to make a case for God would work only because believing in the Bible is lead by believing in God (though a non-believer can agree with aspects in the Bible like the Ex. 20:13 or Ex. 20:15). Although if I made a case like "Abraham believe in God's goodness, therefore God exists," that wouldn't make sense to an Atheist because he'd most likely respond "Just because Abraham believe that God is good doesn't mean that God exists. Abraham could have believe that God didn't care and it still wouldn't be a case for God's existence."
If a Muslim were to say "The Quran says that Abrahan believe that Allah was just, therefore Islam's understanding of Allah is the right one," that wouldn't make sense. Both scenarios are people making a circular argument. If I argued with a Muslim and said "Abraham believe in the Judeo God because it says so in the Bible," and the Muslim responded, "But the Quran says that Abrahan believed in Allah of our book," then we both haven't gotten to the heart of the matter; which book is the book of truth? We are each expecting the other person to already accept the other person's book as fact when our argument is supposed to lead up to which person's book is factual.
By no means am I saying that the Bible can't be used in a discussion of God's existence -- we can use examples from the Scriptures to reference what we understand mercy and justice to be and then explain how God is both merciful and just (since some Atheists use that as an argument against God: "How can God be both just and merciful?").
I may be opening up so much more in this thread than intended
I sure hope I'm not.
