From the Columbia Journalism Review:
The other effect was that the echo chamber the media now decries was pioneered by Stewart and Colbert. Their liberal politics, half posturing, half genuine, was excluding and asphyxiating. Their more general contempt for every aspect of the democratic political process was the liberal version of the cynicism and the nihilism that helped project Trump into the Oval Office.
Yes, in the darkest days of the Bush years, they were sources of therapy, catharsis, and occasional illumination. But they were mining the same vein of contempt for reality as their counterparts on the other side. Just as the far right learned some tactical lessons from the 1960s’ countercultural left, the crew at Breitbart et al. learned some lessons from the two erstwhile prophets of Comedy Central. Breitbart creation Milos Yiannopoulos’s “Dangerous Faggot” is the dark, twisted underside of Colbert’s creation of the type of bullying, autocratic persona that would be perfectly at home at Breitbart.
