An Idiotic Bit of Legislation

Here is an example of foolishness that doesn't come from Congress.  

Currently, there is a bill before the South Dakota legislature that makes it a Class 1 misdemeanor to alter in any way the South Dakota state seal. Presumably, this would be to print it without the motto "Under God the People Rule" in the banner.

Surely this is notoriously against the First Amendment?

Here's the South Dakota state seal. What do you think?
