Censure yourself, never another. Do not discuss right and wrong.

That quote touches a sore spot on me due to the recent death of Erik Naggum. He was a controversial figure, and I find myself struggling to refrain from discussing whether he was right or wrong; discussions that are certain to turn into time consuming quarrels. It seems like an important struggle because his premature death emphasises that life is too short for quarrelling on the internet.
