The laws of the 13 original states, as well as their respective state constitutions, pre-date the federal constitution. Incest is and was an offense in every state, and like laws of murder, is in the jurisdiction of state, not federal, law.

While its accurate that incest (again like murder) is not mentioned in the constitution--its not accurate to say either is permitted by the constitution, as the constitution assumes and protects the jurisdiction of state law.

If you can say murder is constitutional, then you can say the same for incest--but of course saying such is just ignorant.

I hardly consider it ignorant to say that whatever is not specifically forbidden by the U.S. Constitution is allowed by it, meaning that it is left up to the individual states. Many things which have been forbidden in the past by states were not considered at all in the federal constitution. Spitting on the sidewalk has been forbidden under some local governments but that has nothing whatsoever to do with whether it is allowed by the federal constitution. Comparing incest to murder serves no purpose other than to obscure what is really at question here.
