Well "free thinking" alone is not enough. See, TIME is the thing they want to rob from people.
A WHOLE LOT of freethinking is the key. In such a regimen, you will end up examining the religious and "pagan" aspects, but both are a "religion", so you have not escaped anything. Science and academia are also religions, with "gods" who tell people how and what to think.
So one has to apply TIME to the "problem", because the solution to any real problem, takes time to figure out. Time is the variable they want to reduce on people thinking about avenues that reveal truths.
By reducing TIME, most people won't figure out what is truly going on. By the distractions that rib time, another "message" will be presented to mislead people to the wrong solution.
So a lot of free thinking is what is required, MORE than one puts into ANY OTHER pursuit. Because if one does not put in the prerequisite time, they will never sift off enough hay to get to the truth needle.
And that is why the world is inundated with time wasting, and energy zapping, distractions and cul-de-sacs.
Once thinking is reduced, you know you are in one of the bags of the enemy controllers. Notice how ALL religions devolve into a formulaic set of mindless creeds? THAT is the goal, get people in those dead ends, and let them spin their wheels and get NOWHERE fast. In the process, the stop thinking altogether.
THINKING takes EFFORT, and that EFFORT is painful. But no pain, no gain. Brain pain. They are bettign most people will accept the bliss of no thought, aided by them thinking they already know what they need to know, which ceases more thought on the matter.
