You'd have to ask Alabama, they voted to ban interracial marriage and it was "flipped" by the federal courts when measured against the United States Constitution.
And ya, there is a "pro-discrimination side", it those that want to exclude same-sex couple from Civil Marriage.
BTW - It's not "one person", there is the District Judge, the Cirucuit Judges, and the Supreme Court.
But I notice you failed to provide an answer to the direct question. Have a nice day.
