Christian conservative Mat Staver is calling upon marriage equality opponents to boycott three professional sports teams that support such unions.

The San Francisco Giants, Tampa Bay Rays and New England Patriots are among the 379 companies that have signed on to an amicus brief urging the Supreme Court to strike down state bans on gay marriage.

Staver, founder and chairman of Liberty Counsel, told OneNewsNow that the teams had fallen under the control of “radical ideologues who want to literally undermine our Judeo-Christian values.”

“I think we ought to vote with our dollars and not support those sports entities, those sports organizations, or those businesses that literally are hostile to our faith and to the very foundational values of God's natural created order of man and woman as the union of a husband and wife in marriage,” Staver said. “That's so fundamental. If they can't get that right, how can they get anything else right and how are they deserving of any of our respect or our support?”

Staver said it was a few “radical people who sometimes work their way to the tops of these organizations who push their radical agenda … in your face.”

“But they are radical ideologues who want to literally undermine our Judeo-Christian values,” Staver said. “It's the most serious assault on our family, faith and freedom that we've faced in American history.”
