In recent years, however, 4chan’s trolling campaigns have merged with larger political debates about multiculturalism and diversity. The Gamergate controversy, which tapped into the rich vein of misogyny running through 4chan and included aggressive harassment of women online, provided near unlimited fodder for conspiracy-tinged outrage directed at feminists and advocates of progressive identity politics.

4chan users have relished any opportunity to troll what author Angela Nagle has termed “Tumblr-liberalism,” an emerging online discourse on the left that Nagle notes has reached an “absurd apotheosis with a politics based on the minutiae and gradations of rapidly proliferating identities.” This emerging discourse, which Nagle documents in her new book on the online culture wars, “Kill All Normies,” centers on a culture of mass online callouts, public humiliation, and other efforts to penalize anyone deemed in violation of constantly shifting norms of sensitivity around identity.

In one salient example of the absurdities of this style of liberal discourse, Nagle points to an “antiracist” writer who reacted to the death of a child killed by an alligator to ridicule the “white male entitlement” of his parents.

Some on the political right have seized on such attempts to reflexively mock white people by embracing a newly assertive and aggrieved white identity. For sites such as 4chan, which exists to blow past boundaries, the opportunity to present white identity politics was quickly taken to its logical extreme.
