A gay-rights organization says the religious groups that backed California’s gay-marriage ban are lying about the nature of campaigns waged against it.

Brooklyn, N.Y.-based Truth Wins Out says it will take out a full-page advertisement Thursday in The Salt Lake Tribune under the headline, "Lies in the Name of the Lord."

It’s a response to another full-page ad placed in last Friday’s New York Times by supporters of the California constitutional amendment banning same-sex marriage that passed on Election Day..

The New York Times ad accused opponents of Proposition 8 of waging mob violence.

Truth Wins Out director Wayne Besen says that ad grossly distorted peaceful protests across the country that followed in the wake of the California vote.
