(FORTUNE Magazine) – Leave it to . . . the American Civil Liberties Union to get out a provocative message at Chicago's 25th Annual Gay and Lesbian Pride Parade . . . ''A-C-L-U. We defend your right to screw,'' ACLU parade participants chanted as their decorated pickup truck crawled along the . . . parade route. ''Actually, it's our message for the day,'' said Valerie Phillips, the ACLU's public information director. The ACLU, which had about 25 to 30 parade participants on the truck, has been part of the colorful event since 1989 . . . ''I don't know the exact origins of that slogan,'' Phillips said. ''One of our volunteers came up with it. It's not that we sat down and thought about it.'' -- From an article in the Chicago Daily Law Bulletin.
