The many expressions of Freedom of Speech can be seen, heard and watched almost everywhere in daily life.
Many people take it for granted because it's always been there in our lifetime.
Now and then, an issue arises under the mantle of freedom of speech which bothers people enough to take a case to court. While they might have a good reason to oppose it, not everyone will see their point or agree with it. Even if the court renders a decision, not everyone is completely satisfied, and they continue to protest through their own means. All have rekindled the discussion of what is protected under free speech. The level of tolerance seems to run in a giant decade-spanning cycle.
