What are the responsibilities of and challanges to the Freedom of speech in the 21st century?

Our responsibility is to think what we say. Words can make World a better place or even destroy it. By words we can affect the World. Because of that, we have to be very careful by using them . Using words wrong , we can hurt very many people and ourselves too.
When we use wrong words at the wrong time, we can hurt somebody very bad. We can insult people or make them suffer. And this can bay back very hard . For example the event what took place in Kauhajaki school, where one young guy named Juhani Saari , who killed very many his fellow pupils and himself too. This disaster took place because other pupils taunted and japed him.
Religion is in the 21st century very disunited. This makes society acceptive to every little suasions. At the same point education is very easy to get. And when some malevolent human studyes psychology, can he or she manipulate whit other humans and that way he or she can create his or her new religion. And the end of this religion could be very tragic and it could end with very many deaths and suicides, just because somebody tells it is the only right way. For example in the Guyana jungle were founded 914 corpses. They were reverend Jim Jones commanded Folks Temple sects members. Jim Jones used academic psychology to manipulate with them.
Abnormal freedom of speech gives in economy big opportunityes to cause a big changes . For example advertisement in tv, journalism and at the streets. When everywhere will be glorifyed some goods or service , then people will buy it. For example - property. Everybody buyed houses and flats or builded by themselves. But now they are in trouble. They have big debts, and now, with this economic crisis, wery many of them have lost their yobs and have trouble to baying their bills . Soon they will lose their homes . They will be living in the streets and eating from the garbage can. Weakest persons will end their lives in very sad way, because they do not know how to manage their lives. The economic crisis are because people lend themselves through . They live over their capability just because they want to be better than the other, or be as good as the others . And this is caused by advertisment too.
The Freedom of speech is very actual theme in nowadays . Very many humans have suffered because everybody have right to say what they are thinking and express their feelings . In the 21st century, humans are very easy to affect, and because of that we should curtail the Freedom of speech. When we not do that, it could end in very bad way. When humans have too much freedom, they go crazy. The more you give, the more they want. All the wars are causedbecause of the greediness and the Freedom of speech. This will all end when people start to thinking what they are saying.
