CSE HAS NO COPYRIGHTS
Go to "Search" select "name" and type "Hovind". You'll get 25 registered copyrights...none of which belong to Kent or Eric. Type "Creation Science Evangelism" as the name, you get nothing.
In other words, they say they have a copyright, but in reality, they never registered one. They don't have a leg to stand on.
I made a quick video on this here: http://www.youtube.com/watch?v=CDC20R-lX-w
