Citing DOMA, the U.S. government says that it would be illegal to count same-sex partners and identify them as gay and lesbian couples, since same-sex unions aren't recognized on a federal level. Moreover, for same-sex couples who have children, the injustice is even graver. Same-sex couples with kids won't even be listed as "families" on the 2010 U.S. census, and children will be listed as "belonging to single parents."
