I do not have a problem with people expressing their views, in fact I feel everyone should have the right to freely voice out what they think and feel.
The problem starts when the moment we express our views ( and that too in a very polite manner ) the other will reciprocate with unnecessary sarcasm, abusive language and ridicule. They make it their goal to either convince the other that THEIR view is the only right view or silence the other.
It's your right to disagree with another but that can be done in a graceful way too.
And silence should never be taken as submission.
And debates are all about speaking, expressing, and hearing the other.
They are not about shouting, suppressing the other's voice, not hearing another's view point and in general creating noise.
Social media gives us the freedom to express and interact. It saddens me when I see people becoming abusive on Twitter, Facebook and whatsapp.
I guess John Stuart Mill said it well:
"The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error."
