Gregory's ServerI don't actually see much difference between economical propaganda (advertising, marketing), political propaganda (well, this is what we usual call propaganda, but sometimes also "political marketing"!) and religious propaganda (evangelisation or whatever it is called). They are all memes spreading, but it would be interesting to research, if different branches of propaganda stimulate different parts of brain or release different neurotransmitters, or so.
That saying, I must admit that myself I also participated in economical propaganda (being local internet service provider) and political propaganda (cannabis legalisation when I was younger, Pirate party more recently).
But I don't see any easy way out. All sofisticated ways of participation in certain more sofisticated social interactions involve certain level of propaganda or at least self-marketing. Some basic levels are mere "product placement", but beyond certain level, it is definitely manipulation and brainwashing.
