You should read what I said before you try getting snarky with me.
It would be really simple to prove me wrong, all you have to do is find a single example of any state law being overturned as the result of a 1oth Amendment challenge. I will state right now that not only will you not find any such example, you won't even find an example of a state law being challenged on 10th Amendment grounds.
The 10th amendment contains 2 provisions for which powers are granted to the States:
1. Powers not delegated to the United States by the Constitution, and,
2. Nor prohibited by it to the States.
The 'it' above refers to the Constitution. If the Constitution prohibits the States from having a power,
then they don't get that power. Passing any unconstitutional law would fall under that prohibition.
States cannot for example ban personal ownership of firearms, because the Constitution prohibits states from having the power to do that, because the 2nd Amendment is a constitutional protection against such a ban,
the 10th Amendment and 'states' rights' notwithstanding.
