Courts absolutely can nullify laws. That's one of the major purposes of the SCOTUS. And you think this SCOTUS would hesitate to just declare such a law unconstitutional?

Of course the courts can but in practice never do. The 2A community has been dealing with the courts reticence to deal with patently unconstitutional laws for the last 100 years.

Yes and your suggestion otherwise betrays your ill informed idea of how this current court has ruled.

They were practically hand picked to oppose the case law of the two pro-abortion decisions. Their other opinions are broadly _judicially_ conservative which means exactly what you're asking, a hesitancy to nullify laws.

Their opposition to the abortion rulings is largely formed out of a hesitancy to act as pseudo-legilatures. They would not overturn a law that was passed by the government unless it was blatantly unconditional.
