The Federal Government cannot pass any law that conflict with the Constitution or it can be struck down.<quoted text>
You are such an idiot.
The states cannot pass any laws that conflict with the US Constitution or they can be stricken down. DUH
Do you have any clue as to the functioning of the Supreme Court??
That's the court that declared Obamacare Constitutionally acceptable, and declared Jim Crow Laws unConstitutional.(1954)
This is just another version of Jim Crow.
Your comprehension of the Constitution is a mile wide and an inch deep. In other words, stick to truck driving for Airborne Express.
They can pass any law they want and enforce it until the Federal or even the State Courts(for state laws) say it is UN-Constitutional.
This is like telling someone they cannot speed even though their car goes 140MPH "Ya Right"
So in essence any stupid law can be passes, sad but true.
