And by the way, Sullivan’s posts today depend upon there being a difference in tendency toward monogamy between gays and lesbians. How do we explain that difference? Obviously, it has to do with differing attitudes toward sex and coupling among men and women. But that just confirms that women–not the law–domesticate men. Again, the law can reinforce the domesticating effect of heterosexual coupling, but it cannot, by itself, mimic it. So Sullivan’s optimism about gay marriage and monogamy is unjustified. And if that’s true, then his own stated fears for heterosexual marriage would inevitably kick in.
