Interesting that this group of "free thinkers" would strive to censor what others wish to think about.
The separation of church and state is the most misquoted statement used by these groups. It was never meant to keep the church from being a part of what went on in government or their communities. It was used exclusively to keep the government out of the church's business.
The United States constitution says, "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof."
Seems to me this group is trying to prevent others from expressing what they believe in.
If parents and kids want to enjoy seeing Charlie Brown live on stage, no matter where it is presented, why is that a problem? What are they afraid will happen? Just maybe everyone else will learn to think for themselves instead of being forced to think like everyone else.
Who are they kidding when they claim to be free thinkers yet demand others think just like them?
