If you think it's good practice to trust billionaires and politicians and the media, I'm not sure what to tell you. That's a bad plan for life.
I'm not on facebook. Conspiracy has nothing to do with it - general ineptitude and a system that rewards selling fear has everything to do with it. From CNN to Fox, they are all in the business to sell you a problem and to drag along the solution that only they can provide if you continue to tune in. Is it a conspiracy? I mean, sure - but it isn't like they are even trying to hide it - it's their published and open business model. I don't think of it as they are trying to manipulate you as much as you are asking to be manipulated.
If that's not the definition of being a sheep, I'm not sure what is.
