Disinformation (Wikipedia) is probably the biggest danger to society & greatest tool for anyone with the major influence (or cash) to spread the lies.
We all need to guard ourselves from this, as it happens on all levels and in all spheres of knowlege.
This might sound like paranoia, but .. lets all just decide today to check the facts once in a while. At least you ll be able to say – “Thats correct, I checked it” instead of “Thats correct – The media told me so!”
