Nelson Re: "The wrong message" (Editorial, Feb. 27): Due to its content, the comic "Doonesbury" appears on your Opinion pages. Perhaps your editorial, which scolded us ("We are all to blame for kids smoking and drinking") for not practicing what we preach, should appear with the comics. I can only expect your editorial to mean that the Union-Tribune no longer will be accepting advertisements from alcohol or tobacco producers. Sure. Craig A. Nelson Cardiff by-the-Sea
