Letter to the editor: Middle-class families in wealthy nations are often criticized for the ecological damage resulting from their lifestyles. This criticism should not be taken too seriously, however, since its source is often a movie star or celebrity whose own lifestyle would, if widely adopted, destroy the environment and deplete our resources in a short time.
The reasoning in the letter to the editor is vulnerable to criticism in that it takes failure to act consistently with a belief as an indication of the sincerity with which that belief is held.
