DEFENSE OF MARRIAGE: It is not bigotry to insist that there is a good reason why marriage has existed in every known human society, and why it has always involved the uniting of men and women. It is not bigotry to acknowledge what reams of scholarship confirm: Family structure matters, and children are more likely to suffer problems when they are not raised by their married mothers and fathers. It is not bigotry to resist the dishonest comparison of same-sex marriage to interracial marriage -- skin color has nothing to do with wedlock, while sex is fundamental to it. And it is not bigotry to fear that a social change as radical as same-sex marriage could lead to grave and unintended consequences, from the persecution of religious institutions to a growing clamor for legalizing polygamy. -- Jeff Jacoby
