Substanantive Due Process: What are the fruits of this 'poisonous tree'?

Clarence Thomas, legal colossus of our time, has stated that overturning Roe should just be the beginning. The right to access contraception, to marry a person of the same sex, or to generate friction between incorrect body parts with another human, all must go. But is this enough? What other offenses against the constitution must go? Inter-racial marraige? (Tough break, Ginnie.) Publishing literature that encourages or depicts any of the above? Assembly of groups that wish to oppose the will of the Supreme Court? Whose due process protections must be stamped out next? I am asking what non-obvious extremist SCOTUS opinions are likely next to be given the force of law.

Are there any lawmakers of influence openly calling for an end to gay, or same sex, marriage?
