The states cannot trample on the bill of rights.
They do not have that power or authority.
Incorporating the bill of rights against the states means they have to abide by it too.
The FedGov must abide by it.
That they currently do not is because the people are too busy playing at being citizens rather than being citizens.
The supreme court exists to debate law and act as a check on presidential power.
Nothing in the Constitution gives the feds the power to enforce the first ten amendments. The states are limited only by those limitations expressly enumerated in the Constitution proper and the 14th Amendment forbidding state segregation laws against blacks. So you are inventing federal powers not in the Constitution if you say that the feds may enforce it upon the states other than those exceptions.
