Yeah, well the Amendment are only valid in the US of A. Freedom is interpreted somewhat differently from one country to the other.
In Canada, it's very vague, and that's why the judges in Supreme Court have a pretty safe job.
Part I of our Constitution Act, commonly refered to the Canadian Charter of Rights and Liberties start like this:
Rights and freedoms in Canada
1. The Canadian Charter of Rights and Freedoms guarantees the rights and freedoms set out in it subject only to such reasonable limits prescribed by law as can be demonstrably justified in a free and democratic society.
Fundamental freedoms
2. Everyone has the following fundamental freedoms:
(a) freedom of conscience and religion;
(

freedom of thought, belief, opinion and expression, including freedom of the press and other media of communication;
(c) freedom of peaceful assembly; and
(d) freedom of association.
And the different liberties garanteed in the constitution go on into 34 points... But the bit about freedom of speech is what you see above, in item (

of the second point... but is restricted by the point 1. No wonder constitutional judges and lawyers are paid millions.
