"In six months President Obama and the Democratic-led Congress have forced on the American people the most radical and and immoral agenda," said Mathew Staver, founder and chairman of Liberty Counsel.
A key Senate vote during the wee hours when most Americans were asleep has added the so-called "hate crimes" plan, which creates federal protections and privileges homosexuals and others who have chosen alternative sexual lifestyles, to a defense spending bill.
While there are procedural hurdles yet, opponents say they expect the proposal that essentially makes homosexuals a protected class of citizens in the United States soon will reach the desk of President Obama, who has lobbied for it.
But the vote prompted both a warning about what a law linking criminal behavior to thought would do to free speech and a promise that the nation won't give up its citizens' basic rights easily.
"The administration and the Democratic-led Congress are out of touch with the mainstream. They represent the most fringe extreme elements of America. They will not be able to continue their efforts to undermine moral values, socialize the economy and trash American pride and heritage.
"The people will not remain silent forever," he said.
