The Dover case is rather special because of all the lying (excuse me,"inconsistent testifying") that went on in the school board meetings. The Dover case is particularly loathsome because the school board recommended "Pandas" as an alternative textbook.
The Georgia case is merely amusing. It will just create a divide within the student body like exising divides, such as nerds and jocks.
I really wouldn't care much if parents want to cripple their kids with YEC, except my brother did that to his kids. When they got out of high school and into the real world, the shock was so great they pretty much dropped out of society. They no longer speak to their father. Interestingly, they're fine talking to me.
We part company here. My parents raised all 5 of us Catholic beginning 55 years ago with all that entailed in those days. We all remain Catholic with a firm belief in Gods creation and if test scores are any indication, none of us suffered any deficiencies because we were taught that God created the universe as described in genesis.
I'm sorry that your nieces/nephews don't speak to their father but the argument in general has no merit.
