We have become so lost in fantasy to look for reality, yet we never fully indulge in the fantasy either, so what is the point of not living in the present, thinking for yourself, accepting nothing as truth.
Documentaries are the worst offender of taking your view of reality and skewing it toward their view. Such as segments where they ask random people on the street a certain question and record their answer, when viewed as part of the final product you are not getting all the answers you are just getting the side that supports their view on a specific topic. With all the edits and quick cuts you can make anyone say just about anything you want them to, and they don’t even need to actually say! you just make them imply it.
And just about any documentary that presents both sides of the argument will still only show one side in a negative light and the other in a positive one. Even the numerical statistics are seldom sourced.
The point is, take no word as absolute fact even if the evidence seems to point entirely in one direction. Research anything for yourself before you accept it and share it.
