It is more about the "how" and less about the "what".
If I called you 500 times and simply said "Hello, hello, hello", that is still harassment. The WBC people apply for permits and protest on public property. What they say isn't relevant.
In general, your actions and intent are more germane than the content of your speech. That's a concept critical to free speech -- controversial or offensive is far more important to protect than typical conversation.
