actually that statement of the original post would be directly against the 1st Amendment. It allows everyone, even the dumb asses to say what the want (and that's not my opinion)
Unless the government is preventing you from saying it...nothing is being violated
The government may not: a) prohibit one’s own expression; b) prevent one from receiving another’s expression; c) compel one to express certain views; d) foster adherence to an ideological viewpoint; or, e) compel one to subsidize speech to which one objects. It is the right to express one’s beliefs, without any form of governmental interference, that is at the heart of “free speech.”
(there are exceptions..i.e. hate speech, slander, safety and some health concerns) but who determines what those statements are...well people are given PhD's and Nobel's to try and figure it out.
You can say whatever you want, the same with I can criticize as much as I want of what you say....and I wouldn't be labelled against free speech
