My earlier post was meant to define the context of propaganda, not start a tangential discussion about it. That being said, I was not calling the article propaganda nor saying that it was not propaganda; I was merely trying to define what propaganda is in the context it was used previously in the thread and trying to establish that the truth can be propaganda, if used as such.
Further, it is true that every op-ed piece is propaganda, so long as it attempts to make a point (which is the only type of op-ed worth publishing). It is also true that the truth can be propaganda, because while truth isn't necessarily subjective, its revelation can be used to change opinions and attitudes towards something--hence the phrase, "The greatest trick the Devil ever pulled was convincing the world that he didn't exist."
Lastly, I did make up that definition. I extrapolated from the definitions provided by reference.dictionary.com.
You have my apologies for the threadjacking.
