"Believe whatever the establishment tells them."
What establishment? We have an establishment that claims that the government is out to slowly kill us all off and turn of into robots and you have an establishment that tells us that the people who claim that are paranoid freaks?
My point is, we all are sheep from someones prospective.
For example, the guy that is standing in times square selling overpriced t-shirts for $30 sees his customers as idiot sheep for paying this silly money when 2 blocks over the same shirt goes for $3.
But the guy who sells the times square his shirts and the person renting him out the place might be calling him a sheep because they are rigging stuff that he has no clue about.
In some ways we are all sheep, at this very moment EVERYONE here is being conned, financially, mentally or a mix of both. Just like you realize now (hopefully) that certain things you did or believed in 5 years ago was a con, the same thing will happen in some time about events taking place in your life now. We continue to be sheep because we subscribe to the idea that "5 years ago I knew nothing about life, now I know it all, if only I knew then what I know now".
