I honestly do not care if Congress made the modification or not . But saying “it can be repealed” (though I think you meant reversed) and thus you’re unequal is silly.
Nobody has ever sought to reverse the decision, and such a suggestion would be as popular as leprosy (fortunately).
Furthermore, the same way a legal precedent can be reversed a law can be repealed. So what difference woukd that make? This sounds like somebody with $10 million in the bank saying “I’m not a millionaire because I may get robbed”.
Please stop looking for molehills to turn into mountains.
