The first time was to get people to take the vaccine and boosters to lower their immune system response. It was also to yell wolf when it was really a pussy cat. As a result no one pays any attention when the wolf really does come and people are yelling wolf.
People learn the wrong lessons from these events. The lesson is not that there is no such thing as a wolf, or that we should ignore warnings. The lesson was to identify who the liars were and stop listening to them. The MSM were the liars, they are not the ones crying out this time.
The people who were ignored last time were the common people, not the "experts". So the lesson was to not ignore the concerns of common people because "experts" tell you to ignore them. Who is crying wolf now? Not the MSM it is the common people.
