The only amendment that has been repealed is prohibition.
It was repealed because it was hugely unpopular, totally ineffective and a large factor in increasing the power of the Mafia in the USA.
It was passed in the first place because of misguided nonsense paraded by well-meaning moralistic busybodies.
Sort of like the war on the (rest of) drugs .... except many of those are still illegal and they were not part of a constitutional amendment.
