[Sacho]

What you're saying is true - freedom of speech is not absolute, and there are well recognized, narrow exceptions to the First Amendment.

That said, Schenck is an awful example of them, considering:

- it does not advance your argument at all - Schenck was an anti-war protester who was trying to distribute flyers. Where's the "impinging on safety or rights of another citizen" there?

- it has been rejected and abandoned as a doctrine, most notably via Brandenburg vs Ohio.
