It is really, really scary to see how media is constantly manipulated and some truly scary, but still rare events are magnified and repeatedly used for more or less racist generalization. There are tons of examples, even including photoshopped images that get circulated, even in daily press and on TV news broadcasting, with text inserted into placards at protests etc. Never before has it been done at this scale, although propaganda has always been important.
The worst of it all is that the real issues are obscured and lose validity and credibility when reported, as it is hidden underneath tons of bullshit and THAT I think is really, really dangerous. It is a great way of keeping people in control though, through fear mongering.
