Subsequent to the enactment of the 14th Amendment, which the USSC ruled applied the Bill of Rights and beyond to acts of the states (by fiat I would add), STATES as well as Congress cannot limit speech. Yet the 1st Amendment only prohibits acts of CONGRESS. The Constitution is not your Great Great Great Grandfather's Constitution. It's now wax nose imposed on us by judicial activism. Thus a literal interpretation of the 1st would give states free reign to act as they saw fit to regulate speech. See why the strict contructionism goes nowhere?
