Stacy Westly says discriminating against smokers is like discriminating against other activities (“Clearing the air,” Letters to the Editor, Oct. 7). Not quite. If you chug down a bottle of booze, I don’t get drunk. If you eat a dozen Big Macs, it doesn’t make me fat. Smoking is another thing entirely. Smoking stinks up everywhere, it is poisonous, and while legal, is not needed to live. The rights of people to breathe outweigh the right to smoke. If smokers don’t like it, tough.
