No one is calling for interracial marriage to be made illegal. Pro-lifers don’t want to make interracial marriage illegal. Upwards of 94% of Americans agree with it.
What state has passed a law to make it illegal that would result in a lawsuit to even get to the Court? The answer is none. No state is even proposing to do such a thing, and in no state does such a proposal have popular support.
Samuel L. Jackson doesn’t even know how a case gets to the Supreme Court to be ruled on in the first place, apparently.
