“We believe that free communication is essential to the preservation of a free society and a creative culture.”

addressing one of the required elements

It depends on what they mean by "communication".

Free communication is essential to a free society, as the quote says, but it may be restricted to appropriate times and places, and to content that is not libelous; but the concept of allowing all ideas to be expressed cannot be banned.

Clear enough.

When we see crimes being punished more harshly because they are "hate crimes" and "hate speech" then we are seeing thoughts and communications being punished in addition to the action. It is becoming more common, therefore our society must be ever less free and our culture less creative.

YES!!!
