Oh
@Fred Gunner. Never throw a red flag in front of a bull.
Here are the facts.
1. Freedom of Speech was not "enshrined" in your constitution, at least not when it was written. There is no mention of free speech there at all. Not a word. Freedom of speech is addressed in Article 1 of the Bill of Rights, which was an amendment to the constitution. It didn't become effective until 1791, some years after the adoption of the Constitution.
2. On top of that, nowhere in the Bill of Rights does it say that Americans have a right to free speech or that it is a "natural right". Note the words are these:
"Congress shall make no law . . . abridging the freedom of speech, or of the press."
In Canada's written constitution (adopted much more recently than the US Constitution, admittedly) it says this in part:
Everyone has the following fundamental freedoms:
(a) freedom of conscience . . .;
(b) freedom of thought, belief, opinion and expression, including freedom of the press and other media of communication;
One says that the government won't make any law abridging free speech. It says nothing about a right, natural or otherwise, to free speech. The other says that everyone has, sort of like you were born with it (or you might even say a natural right) as a fundamental freedom "freedom of conscience . . . thought, belief, opinion and expression.
Which form of expression of the right would you say is better?
3. The US Supreme Court has carved out a bunch of exceptions to American's right to free speech, including these: speech characterized as incitement (to violence, among other things), false statements of fact, "fighting words" , some forms of commercial speech, some forms of porn, among others. In fact, US courts recently (2017) carved out a new exception for incitement to suicide. Your speech can be, and is, being limited . . .
No right, including your rights under the US Constitution, or ours in Canada, are absolute.
But credit where credit is due. At the time that the US Constitution was adopted (1787), it was rightly seen as a radical document, setting forth a challenge to the "old order" and fundamentally changing the relationship between the government and the governed. We also need to give credit, of course, to the French, who provided the intellectual underpinnings for the French Revolution and to a great extent to the US Constitution.
But I still think that the wording in the Canadian Constitution better reflects your idea of natural rights than does the wording in your constitution. But that's just me, and I don't feel the need to tell everyone that mine is better than theirs (but I will defend mine if called upon).
