Egoism / Egomania is what makes forbidden communications
Egoism of "kill the people who don't agree with our perfect religion book and believe in imperfect books" is welcome free speech in most societies. Hate-speech is not forbidden speech. What gets Dr. Martin Luther King Jr murdered is "all people are equal" speech. If you run a HDTV news network like "Russia Today" that says: Murder and kill those people in Ukraine, such death-wish speech is perfectly allowed by society.
Hate Speech gets you moved to the top of Russia, Vlad Putin in power. Hate Speech gets Adolph Hitler to the top of Germany society in 1933.
Malala who speaks "love all people", she got a bullet put into her head by the Taliban. That's against the egoism of the Taliban that one book is perfect and no other book or education learning of women from other books is important. It is a society of egomaniacs like the Taliban in Pakistan and Afghanistan who don't allow free education and "free speech", "freedom of education", "freedom of speech".
What would military be without "how to murder and kill free speech"? It is the people like Malala who speak of compassion that get the bullets in the brain.
