All the above
Propaganda to promote themselves and to the world
Censorship <span>the suppression or prohibition of any parts of books, films, news, etc. that are considered obscene, politically unacceptable, or a threat to security.

<span>It is false that it is important to have critical friends around in order to strengthen your self-esteem. Quite the opposite - it is imporant to have supportive friends who will always be there for you to help you no matter what - this is what builds self-esteem, and not "friends" who are constantly criticizing everything about you. I believe that would have the opposite effect, making you feel miserable and lonely.</span>
