Gays and lesbians are not entitled to the same heightened legal protection and scrutiny against discrimination as racial minorities and women in part because they are far from politically powerless and have ample ability to influence lawmakers, lawyers for a U.S. House of Representatives group said in a federal court filing.

... "A spate of recent news stories only confirms the conclusion that homosexuals are far from politically powerless," the filing reads.

... "gays and lesbians cannot be labeled `politically powerless' without draining that phrase of all meaning," it says, arguing that the court should deny Golinski's motion for summary judgment in her favor.

The administration [has] characterized gays and lesbians as minorities with limited political power. It had previously said it would not defend the marriage act.

The House's Bipartisan Legal Advisory Group has stepped in to defend it.
