"even FarSight Team-Member Aziz Brown did say that they are a propaganda-outlet."

Okay, let's define propaganda first:

Propaganda is communication that is primarily used to influence or persuade an audience to further an agenda, which may not be objective and may be selectively presenting facts to encourage a particular synthesis or perception, or using loaded language to produce an emotional rather than a rational response to the information that is being presented.

- Not objective means subjective, which means it can deviate from the truth.
- Selectively presenting facts means lying by omission. Facts are hold back so people can't make an informed decision.
- Appealing to emotions to prevent a rational response is psychic manipulation.

Just telling the truth isn't propaganda.

According to Courtney, social sciences is the cutting edge science in the galaxy. But what do they study? There's two possibilities:

1. The reaction of people to truth.
2. The reaction of people to lies.

Then there's the social engineers who want to use social science to control people. They want to shape societies in order to achieve a goal that couldn't be achieved by individuals. This can be done with truth and lies. So let's compare societies that are built on these foundations in principle:

1. The society built on truth

It starts with the truth about what the individual is. Its nature. How can the individual be affected through information to do or not do certain things? How does a belief system work? In a society built on truth, the social scientists would teach people how propaganda and psychic manipulation works, so the people can defend themselves. The goal is individual freedom. If the individual isn't free, the society can't be free, because individuals are the foundation of societies.

This boils down to one simple rule: A free society doesn't enforce membership.

2. The society built on lies

It starts with lies about what the individual is. Specific lies about the nature of individuals, like, people are inherently good or bad, for instance. This is called framing. There's no free will of the individual. You already belong to a group just by existence. The goal is to make people accept their "lot in life", and to create societies where some people have more "rights" than others. This has nothing to do with rights, but with privilege, which is used to control behavior. The free will of the individual doesn't count, because the group "owns" the individual.

This boils down to one simple rule: An unfree society does enforce membership, either through direct violence, or deception.

Unfree societies are always built on fear, because the leaders of those societies fear to lose the members they want to own, and they fear being owned themselves. Because of this fear, they are willing to lie and deceive, as if truth would enslave them if they didn't control society.

Let's break it down further:
Propaganda: Latin "propagare" = to spread
first used in the church context: propaganda fide - to spread the belief
It is adressing the masses, not just a single individual.
In a more modern context it is about how to shape the perception of the masses.
We filter our peceptions through our belive system/expectations how (our individual) reality "normally" looks like. This done by comparing the existing schemes with what we get as sensory impressions from our environment. Ther can be a match or a mismatch. If there is a match, then we reinforce that scheme. If it is a mismatch then we get aroused, may have fear or will dismiss it. Or we might go through a learning process to create a new scheme or remodify the scheme. That is positive. If we cannot create a new scheme or bring the impression into any other existing scheme, then we will avoid or dismiss that impression.
We have many different types of schemes already build from our childhood on. Like how to bind a shoelace (you do not think about it, you just do it). Object schemes (house, tree, etc.), behavior schemes (attack, flee, shout, cry, ...), personality schemes (student, grandma, ...) and so on. The earlier a scheme has been created and the more often there had been a match, the more often it will be used to compare again. A match is always positive confirmation that what the scheme says is right...
Propaganda is actually the way to create certain schemes within the masses. Through fear and scheme incongruencies (attention for the message) and through repetition, best done in early childhood (church, prayers, Hitler Youth, Communist Pioneers, Russia, Russia, Russia).
Farsight is trying to implement (among others) the schemes that RV is possible and hepful into a wider audience/humanity. That is propaganda.
Now we may discuss whether they have the right approaches for the goals.- Or if they should adapt the methods.
