Well, we humans didn't choose to all be sinners by nature, did we? No, if God created us and we are all sinners by nature, it must be God's fault for the design flaw, and thus all sinners would be really innocent.

I gave the idea of God a chance. I really did. For the first 13 or 14 years of my life I was a Christian. But I failed to find any sign of God. He failed to answer my prayers. He failed to show even the slightest sign of his existence. This, combined with the wacky tall tales and outright contradictions found in the Bible (see http://www.skepticsannotatedbible.co...a/by_name.html) caused me to reject the Christian dogma much of my society expected me to unquestioningly accept. Believe me, this was not an easy or impulsive decision (it's hard to tell your parents you no longer believe in their deity). It involved a lot of careful thought and a long period of trying and subsequently rejecting various rationalizations for God's existence. But in the end it was apparent that Christianity had as much proof of its veracity as any other religion did, i.e. none at all.
