Usually the conclusion would be, "Then whom am I to judge?" A non-judgmental society is the goal of those who try to break down our traditional sense of black and white justice.
Then again, if there is no one to judge, then there's no one to judge me if I judge you. That is, if there is no such thing as justice, then there is no such thing as judging, and therefore I can say whatever I want about you, no matter how hateful.
Hence the online culture of hate speech.
