So: A video created and intended to demonstrate how media manipultes news...is itself flaged as "manipulated"?
I do question the intelectual capacity of those who thought this needed the label, or that the label was applicable when considering the video as a whole.
The labelling seems more like an "ignore the man behind the curtain" thing...focus on the "news", ignore the source material, or how its presentation doesn't provide the full (or accurate) story.
Then again, I'm sure there's plenty of partisan people on both sides who are happy to believe unquestioningly what their "betters" tell them, to the detriment of society as a whole.
