If you've got the truth you can demonstrate it. Talking doesn't prove it. - Robert A. Heinlein

“Harry, I need advice.”
“You do? Well, I’ve got it in all sizes. All of it free and all of it worth what it costs, I’m afraid.”

“But what you’re talking about means giving up all that—just the noble primitive, simple and self-sufficient. He’s going to chop down a tree—who sold him the ax? He wants to shoot a deer—who made his gun?...There never was and there never could be a noble simple creature such as you described. He’d be an ignorant savage, with dirt on his skin and lice in his hair. He would work sixteen hours a day to stay alive at all. He’d sleep in a filthy hut on a dirt floor. And his point of view and his mental processes would be just two jumps above an animal.”

Certain types of loudmouthism should be a capital offense among decent people.
