I'm not the parent commenter, and "freedom of speech" is not the same thing as the First Amendment to the U.S. Constitution.
You did. "Freedom of speech."
Freedom of speech is not synonymous with the first amendment.
Yup. "Freedom of Speech" is something you have. "The First Amendment" is a bit of governance that says the US Federal Government has to at least pretend to give a shit about it. If the US Federal Government can't restrict my speech, why should your average butcher, baker, or candlestick maker be able to?
