People react badly to what hurts them.
We can therefore understand why Plato said
"No one is more hated than he who speaks the truth"and Orwell
"The more a society drifts away from truth, the more it will hate those who speak it."Truth-telling stand-up comics such as Bill Hicks are, for their part, an embodiment of the famous quote
"If you're going to tell people the truth, make them laugh, or else they'll kill you."
