At the time of the resistance and de Gaulle there was only the radio but look what a powerful took it was. Now imagine all the tools of propaganda are at the disposals of the brainwashers ;-). Subliminal images on tv during elections campaigns etc...etc... who still knows if his/her thoughts are his/her owns ?
How many people like us take the time to question things ?
When you are in the rat race and pressurized from all sides you don't have time to stop and think and that is where the greatest danger lies....... IMO.
