yes they are.
As a Christian, this saddens me a lot. :(
If you want Christianity to survive, then it is liberal and moderate christians like you that must stand up and publicly denounce this as loud as we do. Other Christians will listen to you far more than they will listen to us.
These people need padded rooms.
I had a friend in college that was a fundie Christian. I just saw him again after a couple years. We hung out and somehow this movie came up in conversation. It turns out that he saw this movie and immediately disassociated himself from his church and is now an atheist.
