He’s right. Nowhere in the Constitution is there an enumerated right to things like privacy or abortion, however Supreme Court cases such as Griswold and Roe interpreted both into law. Once they rule, future cases use those decisions as precedent and further strengthen the interpretation. Short of amending the Constitution and making the previous rulings void, society has little chance of overturning such a decision in the courts. The same thing is going on now with the pro/anti gun crowd. There are just too many cases upholding various legal interpretations. Not saying that the rulings of these examples are morally right or wrong, red/blue, etc. They are just examples of things that are not enumerated anywhere being interpreted into the Constitution and therefore becoming law.
