The Oklahoma law was incredibly broad and absolutist: no Sharia at any time under any circumstances.
It was clearly a violation of the 1st and 14th Amendments, and it was appropriately struck down.
That doesn’t greenlight the full imposition of Sharia. It means that use of aspects of it, so long as permissable under local state Federal law, is ok. Local, state and Federal law is still supreme.
Just like the courts would never say two men or two women can marry or that the courts would say it’s okay to murder your unborn child.
You have way more trust in our judicial system than I do.
