Apparently the reason for the opposition is because they're concerned that the teaching around the event focuses too much on the role Muslim extremism played in the Sept. 11th attacks.

I mean, I do understand. It's unfair to tarnish the good name of Muslims for one devastating attack by radical Amish ideologues, and it's about time we focused on the role of the Amish in this atrocity. They can't keep getting away with it!
