Treaties do NOT supercede the Constitution. Period.
The Constitution says nothing about transporting students out of district to facilitate racial “desegregation” schemes,nor prohibiting prayer in public spaces nor justifying the taking of private real estate to increase tax revenues by “higher” uses, does not guarantee any “right” to dismember, slice and dice the unborn, or to have Mr. Happy traveling up the Hershey highway and masquerading as “marriage” or the “right” of lavender queens to openly serve in the military while being “in your face” or whatever to their fellow soldiers either but you can tell SCOTUS and its subordinate Constitution killing judicial institutions that pretend otherwise.
