Creationists are just old school. Evolution as a theory has been around for about, say, 120 years. Creationism has been around since, well... don't make me say it
. There is going to be a brief period of adjustment.
What is driving the current frenzy of creationists is that Karl Rove found that they are a politically cohesive group that is easily manipulated and so has fanned their flame for political gain. Thats the real drive behind all this creationism nonsense. Now the creationists feel "empowered" and are looking to "do something". There fate is tied to their being a rightwing administration that finds their votes useful. Not that they don't believe this stuff but people believe all sorts of weird things. They just don't vote in blocks so we don;t see them on the national stage.
