Exposure as a propagandist is fatal to the would-be persuader.

The liar wants to be believed, but lying undermines the foundation for credibility.

Aristotle writes that persuasion is based on three things: the ethos, or personal character of the speaker; the pathos, or getting the audience into the right kind of emotional receptivity; and the logos, or the argument itself, carried out by abbreviated syllogisms, or something like deductive syllogisms, and by the use of example.

In a general way, a major goal of the propagandist is to seek some kind of authoritative backing for the belief he or she is propagating.

There are many special interests skilful at manipulating circumstances and communications in such a way as to benefit their own ends and not necessarily the public good.

Any restrictions to freedom of expression will always open the door to possible others, because analogical reasoning can mount arguments showing why this or that class of objects is closely similar to those for which exceptions have been made.

When you give false information you tend to restrict the freedom of choice to others.
