The Overton window has just been shifted.
The repeal of DADT was just a stepping stone to legalizing gay marriage in the United States. ABC News’ Jake Tapper draws out the logically sound argument in a press conference with Obama. He asks, “is it intellectually consistent to say that gays and lesbians should be able to fight and die for this country, but they should not be able to marry the people they love?”
Here is the Mediate video showing Tappers question to Obama, along with Obama’s evasive answer explaining his “constantly evolving” view of gay marriage:
The Overton window is the political theory that uses a window or spectrum to describe public opinion on a particular issue in a given period of time. There is no doubt that with the repeal of DADT progressives are hoping to push the window further left so over time the public will become desensitized on the issue.
In this instance, even if the President comes out and broadly supports gay marriage there is no way it would pass Congress with a Republican controlled House, but with the repeal of DADT the debate will only get louder as time goes on. Without the Overton window moving back to the right (a change in American society and culture) this outcome is inevitable.
