Free speech in the Bill of Rights was specifically intended to allow criticism of government without leading to a charge of sedition. It was never intended to enable falsehood, political or commercial. We've watched the First Amendment acquire the same bizarre absolutism as the Second.
And as a result we have watched dishonest speech get more and more acceptance leading to a president who lied almost every time he spoke and a press that was unwilling to identify lies as what they were.
Free speech should be restored to its narrow and original intent, politicians who lie to use should be shamed into resigning and advertisers who lie to us should go to prison.
