Logical Fallacies Used By Courts to Justify Same-Sex Marriage Validate a Slippery Slope

Abstract:

Scholars have dismissed the argument that same-sex marriage will lead to marriage of three or more, saying it is merely the logical fallacy of the “slippery slope.”  They have also offered various arguments against polygamy to show that same-sex marriage is not a slippery slope.  However, none of the arguments against polygamy are very compelling, especially after Lawrence v. Texas, and the polyamory movement renders most of them moot.  Further, state courts that have established same-sex marriage rights have refuted arguments that the central purpose of marriage is related to procreation and child-rearing, as proponents of traditional marriage have argued.  In doing so, these courts have committed logical fallacies that not only justify same-sex marriage, but that also justify marriage of three or more.  Thus, the marriage-of-three argument is a non-fallacious slippery slope because it predicts a likely outcome of an initial action.

Introduction

Most legally-cognizable arguments defending traditional marriage suggest a link between marriage and both procreation and childrearing.  According to the defendants in Perry v. Schwarzenegger, the federal case challenging the constitutionality of Proposition 8,  “[t]he central purpose of marriage… had always been to promote naturally procreative sexual relationships and to channel them into stable, enduring unions for the sake of producing and raising the next generation.”[1] Advocates of same-sex marriage often deny this alleged central purpose of marriage and point to other benefits and purposes of marriage to justify their argument that the law may not exclude two men or two women from marrying.

Polygamy unleashes a whole series of threats on women, children, even men and gender equality. If same-sex marriage becomes legal in the U.S., we’d better be prepared to defend against polygamy next. This article gives some ways how.

What do the newly released DVD Shark Tales, Dr. Laura and Christianity have in common? They all teach that real love can make a Somebody out of anybody. The movie does its teaching indirectly, while talk-show host Dr. Laura Schlessinger and Christianity just come right out and say it. But these dissimilar cultural icons of Dr. Laura and Oscar the fishy star of Shark Tales are supporting a message basic to Christianity.
