I've studied the unreasoned "dark ages" of the past century.
Oddly, creationism had very little to do with them.
I have very little trouble thinking of many more poisonous ideas being taught to our children in our schools and universities other than the foolish myth of a 10,000 year old Earth.
I've been looking at the past few threads. It's funny the ideas that raise your hackles here, and the ones you just let go by.
