It’s comforting to imagine that people with insane views don’t actually believe them because we’d like to think nobody could actually think like that. The problem is, they do. Lots of them. Just like “birds aren’t real,” it’s easy to imagine no one actually believes that obvious troll but many do! It’s the same tendency that leads us to picture Nazis as inhuman robots instead of actual people who believed that shit. The problem is that rosey view of humanity leaves us open for that shit to happen again.
But laws are interpreted by the courts so a law passed by Congress would still be subject to their interpretation. In fact, even rights outlined in Constitutional amendments are interpreted by the courts. The best option would have been a constitutional amendment that was as specific as possible. However,
A) a constitutional amendment was not needed and should not have been required. The right to abortion was already codified in law and had a large pile of case law backing it up. Should we try to pass amendments for all the unenumerated rights? Do we need a state convention every time the courts rule in a way that establishes a new right?
B) Even that would not have stopped a court that had already made up its mind decades ago. They could have ruled that the new amendment violated the old ones and was void. They could have ruled it only protected abortion in rare cases, or that states rights are more important and overrule the right to abortion.
C) a constitutional amendment was never going to pass to requirements to become law. It would require a Dem supermajority in both chambers or Dem control of 2/3rds of states which is impossible with current gerrymandering.
Fundamentally we are looking at a whole party that would break any rule, law, or norm as long as it lets them do what they want. Establishing more rules or laws just gives them more things to break. The only party at fault here is them.
