According to MADD, a lower drinking age will result in more drinking among 18-to-20-year-olds, which will result in more drunk driving, which will result in more dead teenagers. Therefore, if you favor a lower drinking age, you favor dead teenagers.

There are a couple of problems with this syllogism. First, although MADD insists research "unequivocally shows that the 21 law has reduced drunk driving and underage and binge drinking," the picture is not quite so clear.
