Liberal writer Richard Kim of The Nation welcomes David Blankenhorn's defection on marriage as an opportunity to argue for further destabilizing marriage. For anti-marriage activists like Kim, nothing will ever be enough:

"...The primary difference, of course, is that Blankenhorn and I fundamentally disagree about what marriage should mean—for gays and straights alike. As the founder of the Institute for American Values, Blakenhorn has attacked single mothers, championed federal marriage promotion as welfare policy, railed against cohabitation and no-fault divorce and opposed access to new reproductive technologies. One of his institute’s latest crusades has been against anonymous sperm donors because it leads to “fatherless” children, an abiding preoccupation of his. Suffice to say, I don’t agree with any of this. I think divorce can be a great thing—as anyone leaving an abusive marriage might confirm. And I think all the debates over which type of family produces the best outcomes for children ought to be meaningless as a matter of state policy. Gay or straight, single or married, let’s try to create the conditions in which all families can succeed. Blankenhorn sees an inner circle of honor and benefits that should be attached to marriage, and he’s now extended that circle to include gays and lesbians. I want to scramble that circle."
