Why is it wrong? Those treaties have been around since before you were born. Those are agreements the US Government signed up to and they are considered to have the same relevence as Laws passed by Congress and the Constitution.

From Article Six:
This Constitution, and the laws of the United States which shall be made in pursuance thereof; and all treaties made, or which shall be made, under the authority of the United States, shall be the supreme law of the land; and the judges in every state shall be bound thereby, anything in the Constitution or laws of any State to the contrary notwithstanding.
This goes all the way back to the Founding Fathers. Nothing wrong here.
