Correct. So why is SCOTUS ignoring the Constitution and restricting our rights?
Because those rights are not absolute and reasonable restrictions can be made--threats, libel, slander, obscenity, an officer who conducts a search without a warrant but with the consent of the occupant, pornography, are all examples of actions that can be restricted by the government (federal or state).
Those rights have been greatly expanded over the years. Until 2010 the 2nd did not even apply to states and states could prohibit guns until the court made the 2nd applicable to the states. None of the Bill of Rights applied to the states until 1925 and since that date most of those rights have been made applicable to the states.
