At Roy's place, commenter M.Krebs linked to a blog post about the role that the 4chan message board played in the ascent of Donald Trump. This post is required reading for anyone trying to make sense of the political career of a boorish, idiotic authoritarian.
4chan is the wellspring of much of internet culture, having originated such ubiquitous internet memes as LOLcats, Rickrolling... indeed the typical 'internet meme' with the black-bordered white lettering. The 'no rule' random board /b/, whose users styled themselves as /b/tards, was the place where the channers tried to one-up each other with disturbing images, extreme porn, scatalogical content, Nazi allusions. I've never been a 4chan denizen, being too old and too averse to bad grammar and spelling, but I internet-know a decent fellow who was a 4channer, and he characterized the trolling culture there as 'pissing in an ocean of piss'.
My gut feeling is that much of the anger that led to Gamergate, the 'alt-right', and the Trump election stems from the 4chan 'internet nerd' crowd's anger at having their culture 'co-opted' by normies. When Katy Perry referenced 'their' cartoon frog in a tweet, it caused a lot of outrage among the alt-cognitive. The spite that led to the Trump election is similar- the wholesale rejection of societal norms as a backlash to the 'liberal elite', or 'politically correct' culture. The 'chan' base, the 'anime Nazis', backed Trump because they saw the election of this 'pussy grabber in chief' as a rebuke to the Anita Sarkeesians of the world.
The tragedy of this particular political backlash is that it is rooted in an ephemeral internet culture, but its dire effects will be long-term. The standing of the United States is in jeopardy, as are the civil rights of its residents. Most alarmingly, the planet's ecology is reaching a tipping point while the administration is doubling down on denial. By the time the 'chan klan' grows up and realizes that their actions have real consequences, it will probably be too damn late, but hey, at least they showed those uppity bitches and meme-stealing normies an thing or two.
