I am a bestselling novelist. Words are my profession. So I really hate the Word Police. Beware anyone who tells you what words you can, and can’t use. They only want to control you. That said, when you see somebody using the word “gauche” they’ll usually prove to be a pretentious dipshit. — Larry Correia (Fisking the New York Times’ Modern Man)
