The US Constitution doesn't give you anything. It recognizes that you have the Natural Right to speak your mind. I wish people would stop getting that confused.

It's the same when known people in videos say they have a "First Amendment right" to free speech, or a "Second Amendment right" to bear arms. The Constitution dictates how the government shall operate, and the Bill of Rights is supposed to be shackles on the government, to state what they cannot do to you.
