That was a very moving post. Thank you for sharing it with us, Hangdawg.
It was spiritually devastating for about 3 or 4 more months after I accepted evolution as a plausible theory. That time when I was constantly doubting God and all the Christianity around me was the most depressing period of my life. But I'm definately glad I went through it. I have learned immeasurable amounts of stuff, gained some humility, and a better understanding of Christianity, science, and philosophy in general.
I am sorry you suffered through a spiritual crisis. I have heard that is a very common occurrence for Creationists once they allow for the possibility that Creation is wrong. In fact, I don't think I've met an ex-Creationist yet who didn't go through a point where they questioned their faith and the existence of god.
I think it is one of the most destructive stances YEC organizations take - that one's faith or belief in god must hinges on the belief of a young earth and man/woman's special creation (i.e., Adam and Eve).
In the course of a creation/evolution or young/old earth debate, I do consider the possibility that the arguments may result in someone losing their faith and it pains me. While I did not suffer any such spiritual devastation, I have seen others go through it. Really, though, there's no reason for it because there is always a place for god in people's lives. However, AiG and other Creationist organizations like them make it hard or impossible for the average person to see that.
I think as long as you are polite, patient, and clear that you are not trying to destroy their faith in God and as long as they are willing to have an intelligent discussion you are not wasting your time.
That is very good advice. And just so you know, none of us arguing on the side of evolution wish to destroy anyone's faith. I am happy to hear you managed to retain your faith.
Again, thanks for sharing.
