Attention-grabbing images instead of robust debates

Today, social media further transforms political discourse from reasoned argument to attention-grabbing images and memes.

McLuhan once said that the politician will be too happy to abdicate in favour of his image because the image will be so much more powerful than he will ever be. Some regard modern politics as a fulfilling of McLuhan's prophecy. Democratic societies that neglect the effects of the new forms of media on the quality of political arguments do so at their own peril.
