Social media sites put the power to express ourselves freely in the palm if our hands and on our desktop like never before. I don't see why when given the power to influence decisions and have your opinion why people use it for such pointless negative purposes such as cyber bullying, hate messages and attacks.
I can understand the use of social media for protesting or conducting and promoting controversial discussions because freedom of speech can open doors for educated and constructive debates and conversations.
I do not like the idea of people using social media for attacking people or for hate messages with no structure or simply out of spite or to hurt somebody. This is anti social behaviour and does no good at all.
