Brian Brown, the president of the National Organization for Marriage (NOM), says it's a “slur” to compare the gay marriage movement to the Civil Rights movement.

Appearing on a Meet The Press panel discussing two related cases argued last week at the Supreme Court, Brown disagreed with NBC's Pete Williams' prediction that the high court was not prepared to rule on Proposition 8, California's 2008 voter-approve constitutional amendment which defines marriage as a heterosexual union.

“I don't think that the court is going to punt,” Brown said. “The court is going to answer the question. The question is simple: Do the people of the state of California, do the people of the states of this country, have the right to have their voices heard or is the court going to trash over 50 million votes? The lower court ruling wasn't just about Proposition 8 and what is being brought forward is this myth that somehow embedded in our constitution – something our founders didn't see and we haven't seen up until now – there is a right to redefine the very nature of marriage.”

When asked his thoughts on comparisons to the Civil Right movement, Brown answered: “I think it's a slur on the majority of Americans who stood up to vote for what President Obama a year ago agreed to, Secretary [Hillary] Clinton agreed to two weeks ago, that it takes a man and a woman to make a marriage. It's a slur on them to somehow say that opponents of redefining marriage are in the same boat as those who opposed interracial marriage. That is just a slur. It's an assertion.”
