Oh yeah. Insults lead nowhere. Jerks.
That's the frustrating part; creationists can't all be dismissed as stupid. There are profound socio-cultural blinders they feel compelled to wear no matter what information they have and understand. Ronald L. Numbers book The Creationists gives a fascinating history of creationism and some insight into the origins and persistence of it at least in the U.S. From page 10:
"Rather than finding clerics arrayed in simple opposition to scientists, we discover conflicts of a different sort: psychological, as creationists struggled to reconcile the apparently conflicting claims of science and Scripture; and social, as they quarreled with one another over competing scientific and biblical interpretations or contested the boundaries of science and religion with evolutionists in courthouses, legislative halls, and school-board rooms."
I mention that book because I can see it from where I am and I'm tired and rambling.... yadda yadda yadda...
