I remember a help-wanted ad for a position at the University of Oregon about 20 years ago that ended with "women, minorities, gays and lesbians encouraged to apply." When the department was contacted about the ad's wording implicitly discouraging some from applying, the indignant response was "white men have never needed encouragement to apply for jobs. Everybody knows that." Click. The next call, to the campus EEO office, was met with a very long pause, a polite request to be put on hold and then a supervisor offering thanks in carefully couched language for having been notified.
The reworked ad in the next day's paper didn't encourage anyone to apply.
