The Worst Case Yet Against Gay Marriage

An excerpt from a dissection in The National Review:

Gay marriage may reside outside the kinship system, but it has all the wedding-planning, nest-building fun of marriage but none of its rules or obligations (except the duties that all lovers have toward one another). Gay spouses have none of our guilt about sex-before-marriage. They have no tedious obligations towards in-laws, need never worry about Oedipus or Electra, won't have to face a menacing set of brothers or aunts should they betray their spouse. But without these obligations--why marry? Gay marriage is as good as no marriage at all.

I'd like to see him say this in front of my in-laws...
