The media, owned and controlled by powerful people who benefit from the status quo, just tacked on the term 'far' to remind people not to venture outside the Overton window or think too hard. It's scary and far away. Stay the cosy middle where it's safe. Anyone against the pro-corporate status quo (for example mass immigration) is tainted having an extreme opinion; Discussion over.

There are a few nutters and poor people notice these trends first. The media tend to zoom in on those people and of course that taints all their concerns because normal people don't want to say anything that people might see as poor or nutty; they want to be seen as successful and smart. Only poor people would complain about immigration and only extremists and pedos would complain about censorship and you are not one of them right?
