Volokh on gay marriage slippery slope

There is a misperception among some supporters of gay marriage that the slippery slope argument is itself a logical fallacy. Not true. Some slopes really are slippery. Law professor Eugene Volokh, himself a supporter of same-sex marriage, points out here why those anti-SSM folks who point to the slippery slope on gay civil rights actually have a good point. Excerpt:

Of course, some people might like this slippery slope, because they like what's on the bottom. (See Deb Price, Marriage Is the Only Acceptable Option, S.J. Mercury News, May 23, 2002: "When Hawaii's steps toward legalizing gay marriage led to a backlash in Congress and many states in the mid-'90s, some gay-rights advocates felt the need to pooh-pooh the 'slippery slope' argument by foes that we'd ultimately try to push beyond any piecemeal rights thrown our way and would be satisfied with nothing less than full marriage. But not anymore. 'Our foes kept saying, 'This is a slippery slope to marriage,' and we kept nodding our heads, 'Yep,'' says [Anne] Stanback, unabashedly embracing marriage as the goal, just as do the movement's two top political groups, the Human Rights Campaign and the National Gay and Lesbian Task Force.") I myself support recognition of same-sex marriage as a policy matter. Still others may disapprove of the bottom of the slope, but might see some of the steps down it as morally imperative.

But it seems to me that decisions such as the ones in California, Connecticut, Iowa, Massachusetts, and Vermont ones illustrate that it's a mistake to just factually dismiss the claims that slippage is possible. When we're dealing with a legal system that's built on analogy and precedent (both binding precedent and persuasive precedent), the possibility of a slippery slope has to be taken seriously.

And this is true even though the past decisions are distinguishable from a future one. Employment discrimination laws, for instance, are not the same as same-sex marriage. Legislative decisions are not the same as constitutional ones. It was certainly possible to draw the line between legislative decisions to ban private discrimination in employment and judicial decisions to ban governmental discrimination in deciding who may marry. That two matters are distinguishable does not mean that they will be distinguished by future decisionmakers. And in fact they may influence future decisionmakers even when the earlier decision expressly disclaims any attempt to accomplish what the later decision did, as was the case with the Iowa antidiscrimination statutes, which expressly said that they "shall not be construed to allow marriage between persons of the same sex." Though they themselves weren't construed as allowing same-sex marriage, they were indeed construed as a data point in favor of a constitutional decision allowing same-sex marriage.

So people who worry about slippery slopes generally -- and who worry about slippery slopes in the field of sexual orientation and the law -- can't be lightly dismissed. And it is reasonable for them to worry: If we have gotten this far partly through slippery slope effects, will we slip further, and to what? In particular, would this increase the likelihood of further broadening of antidiscrimination laws? Would it increase the likelihood that groups (such as the Boy Scouts) that discriminate based on sexual orientation will be excluded from tax exemptions, just as groups that discriminate based on race are often excluded from tax exemptions? Would it increase the likelihood that such groups will be excluded from generally available benefits?

Would it increase the likelihood of broader restrictions on anti-homosexuality speech -- in government-run organizations, or in private organizations coerced by government pressure -- by analogy to the broad support in many areas for restrictions on sexist speech? Would it increase the likelihood of restrictions on people's choosing roommates based partly on sexual orientation, or advertising such preferences in "roommates wanted" ads? Would it increase the likelihood of punishment of wedding photographers who refuse to photograph same-sex weddings (even if they have religious objections to participating this way in such ceremonies, and even if they feel that requiring them to photographing same-sex weddings compels them to create artistic works that they do not wish to create)? Would it increase the likelihood that legislatures will repeal religious institutions' partial exemptions from some bans on sexual orientation discrimination in employment?

Of course it would, and it will. Follow the logic, and don't be put off by people who would rather you not follow the logic calling you a fraidy-cat bigot. It's a tactic. And by the way, it would be nice if, right about now, bloggers and journalists who see this for what it is and don't like it would take a public stand, even if it costs them something. Because it's going to cost us all a lot more in the very near future, if something doesn't change.
