The entire COTUS applies to the feds... States were free to do as they seemed fit. That was teh original design/intent.
The ruling is still a win.
Uhm...no.
The Constitution spelled out what the federal government could do and what it couldn`t do,the Bill of Rights and other amendments.
What wasn`t explicitly stated one way or the other was regarded as a states right.
That is why the abortion issue was acted upon by an activist court citing a "penumbra" finding a right of privacy.
They were wrong but had to force it
If what you assert was correct then a state such as mine or yours would have the right to say all conservative speech is forbidden as the right to free speech only applies to federal property.
That is a bizarre and dangerous interpretation of the Constitution.
It would lead to what amounts to a 50 country version of the EU.
