Broughton wrong about smokers

In his viewpoint, "Discrimination: Why do smokers allow it to continue?" (3/30), Michael Broughton asks "Why do smokers allow this to continue when other minorities that suffer the same discrimination would be up in arms protesting?" Someone chooses whether or not to smoke. The laws that "discriminate" against smokers exist to protect people against a major health risk, which is quite unlike discrimination against minorities.
