That was a good post, Joe.
I'd add that parents who are on a mission to keep their children in the faith take a huge risk if they tie that faith to a literal interpretation of the Genesis story.
The evidence for an old earth is undeniable, and the evidence for evolution is growing... So making people choose between the two just creates an unnecessary crisis of faith.
I think you have succinctly defined the nature of this debate and why, despite any advancement in scientific knowledge, it will retain its ferocity.
It is thus b/c many of the adherents to evo. have and will continue to use evo. as an instrument to undermine faith in the Bible and, regardless of their denials, God.
Many people are unhappy that they are forced to pay for an educational philosophy that is at cross purposes to their deepest understandings of life. They will continue to fight it, and they won't stop.
Thank God for their persistence.
