Avoid politeness, be constructively blunt

Henry Louis Mencken at work

There is a difference between being irreverent and offensive. Criticism and confrontation is a cleansing act that helps people and argument to refine and streamline. Just as destruction is not opposite to birth, reform and creation, so impoliteness can be constructive and politeness can be destructive. Don't be destructively polite, be constructively blunt. As Edward Land said: "politeness is the poison of collaboration." Maria Popova echoed this when she said:

"[Refuse] to infest the garden of honest human communication with the Victorian-seeded, American-sprouted weed of pointless politeness."

Thomas Sowell said:

"When you want to help people, you tell the truth. When you want to help yourself, you tell people what they want to hear."
