U.S. Bill of Rights
Article [I.] \13\
Congress shall make no law respecting an establishment of
religion, or prohibiting the free exercise thereof; or
abridging the freedom of speech, or of the press; of the right
of the people peaceably to assemble, and to petition the
Government for a redress of grievances.
**********
Speech and press are explicitly mentioned. Extending the meaning beyond exactly those words is a liberal interpretation. While not all rights are enumerated, only those of particular relevance and which are explicitly protected from government infringement are listed. Exactly that idea is mentioned elsewhere in the document.
Precisely what rights a person may exercise, indeed have, are what the government says they have (or not). That is intended as a statement of my reality, not an ideal that I would necessarily support. I do, however, value society's vote on what crosses the line as not in the best interest of that society. That is surely an imperfect process, especially problematic when religion or an abberational ideology dominates a goverment.
I feel that society's efforts to become increasingly civilized is well supported by the historical record. There has been progress, especially in reducing barbarism, but total freedom to do as one pleases, whether or not others are harmed, should not be cause to keep one awake at night. It ain't gonna happen.
I certainly value the BoR as a line in the sand, beyond which the law may not go. I would support efforts to sharpen the interpretation of where that line may be.
In other words, "freedom of expression" is a fabrication. I think many claims for freedom of speech or even what constitutes "the press" in the spirit of the Constitution are ridiculous.
States or municipalities with freedom to vary from State law should be free to legislate in any manner that does not violate the US Constitution and BoR, exactly as it reads.
Liberal interpretations of the COTUS is why we have such a mess today and certainly why gun owners are constantly on the defensive. The other reason is that Constitutional changes are not easy to make, so instead of going through that process, we rationalize why changes via legislation are somehow supported by existing constitutional provisions. Judges do the same thing with other parts of the law. If what they would like to rule is not supported by the law, they rationalize what the law means or the importance of some precedent. What they are supposed to do is pass, deferring to the legislature for the future, because the law doesn't support their decision. What they actually do is make up some law to support the current case. Thus the "activist" label.
It is never activism, if you like the ruling, right? Wrong!
