Using this logic...Freedom of the Press would be unconstitutional if it wasn’t in the constitution.
The Constitution would be un-Constitutional if it didn't exist.
But just for you and me.
It's really freedom of the [printing] press, meaning freedom to publish.
What we today call "the press" is just a profession based on publishing, but the first amendment was also intended to protect pamphleteering, which is equivalent to Freerepublic, Facebook, and Twitter today.
