Technology with their algorithms allow propaganda to be executed with pinpoint accuracy: that is cheating.
The cheating is the ability to pinpoint the lie.
Propaganda is deliberately spreading ideas, facts or allegations to further one’s cause or to damage an opposing cause.
I think furthering a cause is ok if discussion is allowed. But opposing cause with a goal to damage is not healthy for community and I think that is what Fox News does.
The function of being human is thinking: preferability to create cooperation to create community of thinking.
One should not practice propaganda. Propaganda is brainwashing. Fox News is propaganda in their politics. The other networks are much better but often do NOT have a strong practice of good journalism.
To have a goal to cause damage to another’s idea is very different than a discussion about one’s belief.
