We studied whether the vernaculars of the extremely vitriolic, “politically
incorrect” sub-forum of 4chan/pol/ have crossed over to the comment section
of Breitbart News, a right-wing news website that was found in earlier
research to have played a significant “agenda-setting” role in the 2016 U.S.
presidential elections. We study if crossover exists around both the 2016 and
2020 elections. In our analysis, we find evidence suggestive of such crossover,
centered around the presence first on 4chan and later Breitbart of a series of
racist, antagonistic and otherwise extreme terms. This crossover of 4chan/
pol/’s vitriolic vernacular marks an expansion of hyper-antagonistic “altright”
politics to Breitbart’s more mainstream right-wing populist audience.
