Look g, the Obama stuff has split our people right down the middle.

There are those who believe in the system and have accepted complicity and assimilation. And then there are those who sight fundamental problems from the foundation upwards.

For one thing, seeking info out of the box will cause you to encounter uncomfortable ego-challenging, identity-challenging facts. If one is not prepared to challenge/confront themselves first then they will not be ready to digest conflictory information. That is one of the protectionist features of this society. As long as ones worship their pre-established identity based on pre-conceived notions, they will dismiss the truth and look at it as but unnecessary stress.
