So far as you say Mr. Kapoor, "abuse is the argument" you are absolutely right. But then you try to say, one section argues rationally and the other section shout abuses down at them and that is when I disagree with you.
No one in our political system rationalises. Each political position holds their own views to be correct and does not engage with the other position, instead just simply shouts them. You however seem to be leaving the impression that the Rights rationalise and the Lefts abuse which is incorrect.
