From Justice Scalia's majority opinion in Heller v District of Columbia (2008:
Some have made the argument, bordering on the frivolous, that only those arms in existence in the 18th century are protected by the Second Amendment. We do not interpret constitutional rights that way.
Actually, Justice Scalia, that is exactly the way abortion was interpreted by your SCOTUS descendants in the Dobbs abortion case! Since abortion was not common or completely legal or illegal at the time of enactment of the 14th Amendment (1868) Roe v Wade and Casey v Planned Parenthood were not only "wrong, but egregiously wrong."
