Freedom of speech is a critical human right. The right and freedom to express ones views is what creates a vibrant society. Societies that come to accept all and differ with none become stagnant; unable to remove the tumors of irrelevancy from their fabric. Critical differences, on the other hand, encourage people to question views that have come to be accepted as the absolute truth, leading to refinement of human thought and understanding. It is for this reason that those who understand these underlying principles of free speech must rise to defend it so that humanity at large, including those not in favour of it, can benefit from its consequences.
