Bottom line is - no one can know the entire truth about anything unless they were there in person, when it happened.
That's as basic as it gets.
Relying heavily on information which is at best, second hand, third hand, fourth hand, super corrupted Chinese Whispers hand, is risky.
Too much potential for errors.
It is perfectly possible to find accurate stats, facts and unbiased opinions if you look in the right places.
But, like I said before, only if you are bothered.
By the way I read an interview the other day with an American guy that used to run a fake news website. He said that conservatives swallowed all the crap he fed them while never got anywhere with liberals who would debunk the story by about the third post every time. I'm guessing this is because they were better informed.
ignorance: not a virtue.
But anyway, blather on. I am off to the place I go to talk people who actually give a shit.
