FREEDOM OF SPEECH & EXPRESSION is one of the most fundamental rights that individuals enjoy. It is fundamental to the existence of democracy and the respect of human dignity. It is also one of the most dangerous rights, because freedom of expression means the freedom to express one's discontent with the status quo and the desire to change it. As such, it is one of the most threatened rights, with governments - and even human rights groups - all over the world constantly trying to curtail it.
