Between the last sentence and this one, I sought to confirm this by looking through a Time magazine. Since genocide is the problem in question, the public relations solution can only range from lying to cosmetics. Morrow's remark suggests this is the full range of PR's work. Few, I suspect, would disagree. It seems only fair to defend the profession, but there is no point to it.
Common usage is impossible to correct.
And frankly, there is a much smaller market for telling the truth than for shading it. For proof, check your trash for a computer industry press release. The dishonesty here is a matter of form more than content. Every press release is crafted as a news story, complete with headline, dateline, quotes and so forth. Yet most editors would rather insert a spider in their nose than a press release in their publication.
