Via Pharyngula, last year Louisiana passed the ironically-named "Louisiana Science Education Act", which is basically one in a long string of dumb pieces of legislation used by Creationists to try to sneak religion in the back door of schools. The wording says something about allowing teachers to bring special materials (i.e. non-approved textbook materials) to refute particular "controversial" topics like evolution and global warming.
Many scientific organizations urged our Governor to boycott the bill, but he's a religious conservative so he ignored them and signed it into law. And now it's hurting Louisiana in more ways that one.
The annual meeting of the Society for Integrative and Comparative Biology was going to be held in New Orleans this year, but because of the passing of this moronic bill, the organizers decided to move the venue to Salt Lake City. So the stupidity of this bill basically cost the New Orleans local economy a week's worth of revenue from about 2,000 scientists and students who would have attended the meeting.
So not only is such legislation medieval and educationally-backward, it's economically-damaging. Unless, of course, the hit is offset by religious or creationists groups coming here when they otherwise wouldn't because the state is a haven for science-denial. Good times.
