Can we call it propaganda?

at the point where a terrorist attack that killed 4 americans was whitewashed as random behavior by angry movie critics -- because it happened 5 weeks before a presidential election.

at the point where 300 million Americans are assured that they can keep their doctor if they want to, even though the 10 million cancellation letters have been written, but not yet sent, because it is just a few weeks before a presidential election.

at the point where the rise of terrorist supergroup ISIS is covered up, and in so doing, allowed to continue to grow rapidly and unmolested, because it is a few months before a presidential election.

all of these events, the facts of which are not in dispute, are textbook cases of propaganda.

so, to answer your question, that point was about 4 and a half years ago.
