I actually think most of the crazier sounding stuff in videos you see on the internet is more or less correct (not 100% but a lot of it). I think reality is a lot crazier than fiction.
So, although I used to be completely left-leaning and liberal, now I buy most of it to a certain degree, not just the crazy left stuff -- from the singularity stuff, the zeitgeist stuff, but also a lot of that stuff Alex Jones says (I shouldn't admit that, and I am not sure about a lot of it, for instance I don't think that there are too many vaccines involved in population control, but I can't eliminate the possibility).
What I have learned from the "batshit insane conspiracy theorists", well, a lot of it might be crazy. But I do know that they are right about some things -- governments aren't good to the people, and the United States is no exception, and the crap they tell us about world events on TV is just lies.
Empires didn't just happen for the whole of recorded history and then just suddenly stop around the time that moving pictures came out. I really believe that the American dominance should truly be considered an extension of the British Empire and in many ways has been and continues to be even more brutal and oppressive.
The world bank and the like do exercise economic warfare. The second and third world are exploited and repressed.
You don't have to be crazy to consider things from this point of view. All you have to do is stop subjecting yourself to STOPTHINK. In other words, just realize that "oh, that sounds like a crazy conspiracy theory" is not a reason to put your fingers in your ears.
