You constantly speak as though white people and black people are monolithic groups, which may be why you think the existence of ancient laws in some states is damning to all “white” people. But both black and white people are actually philosophically diverse.

Have you noticed that it’s not 1967 anymore? White people ended anti-miscegenation laws.

You might also want to look up the attitudes of black people in that time. They also thought interracial marriage was wrong. Compare the polls in the 1950s with those today.
