"In both fields the tenets of one man may seem the rankest error to his neighbor. To persuade others to his own point of view, the pleader, as we know, at times resorts to exaggeration, to vilification of men who have been, or are, prominent in church or state, and even to false statement. But the people of this nation have ordained, in the light of history, that, in spite of the probability of excesses and abuses, these liberties are, in the long view, essential to enlightened opinion and right conduct on the part of the citizens of a democracy."
A paragraph from an old Supreme Court case that feels like something some people who ought to know better have forgotten. Boldface added.
