WATCH YOUR MOUTH! It's hard to stay out of trouble because the PC police are so aggressive about what words are acceptable. AMERICA, THE OFFENDED: Do you know the politically correct word for someone who is ugly? Fat? Producer Rikki Ratliff went to Times Square to give people a politically correct quiz. OH NO YOU DIDN'T! What is the politically correct term for blacks? Columnist Deroy Murdock says "African-American" is an awful term, and only people obsessed with race use it. VERY FUNNY : One weapon against the speech police has been comedy. A joke is often funny because it breaks the rules. "The Death of Cool" author Gavin McInnes says political correctness smothers comedy. ACADEMIC CENSORSHIP: College is supposed to prepare you for the real world. But college is anything but the real world. Students are coddled and university administrators jump through hoops not to offend them. OFFICE SENSITIVITY: We have to be careful what we say to our co-workers. How careful? One article explains: You must never use "man" words like "man-power." You must say "work-power" or "staff." You must never say "manmade," it's "synthetic." MY TAKE: I made a career of confronting people, and sometimes that means saying offensive things. I say nasty things sometimes because sometimes truth comes out of it. We learn through confrontation. Science blossomed in America because here, no central authority, no governor, no judge, no Imam can tell people: You may not say that! Ideas compete for acceptance and usually... eventually... better ideas win.
