Our time is marked by a resurgence of hate that threatens to increase oppression. Social media has contributed to this by acting as a medium through which hate speech is spread. How should we model the spread of hate? This article considers two models. First, I consider a simple contagion model. In this model, hate spreads like a virus through a social network. This model, however, fails to capture the fact that people do not acquire hatred from a single infectious (...) contact. Instead, it builds up in a person's beliefs and attitudes through time until the infection reaches a level where the subject themselves becomes a generator of hate speech. Second, to accommodate this, I consider an alternative model known as complex contagion. I argue that not only is a complex contagion model more explanatory and predictive, but it can be used to explain why certain features of social media cause it to be a promoter of hate. I conclude by sketching some mitigation strategies. (shrink)

This paper considers Tirrell’s analysis of toxic speech using examples epitomising speech that are misleading, outright false, and without compelling justification. They are toxic in polluting and eroding democratic functioning. However, I argue that Tirrell’s two epidemiological models (the common source model exemplified by poisons, and the propagated transmission model that viruses exemplify) fail to make good sense of my examples, which are deeply insidious without being overtly invidious. The limitations of the epidemiological models suggest that toxicity is part of (...) our default form of thinking and talking, rather than being an ‘outside’ pathology like a poison or a virus.

We investigate experimentally whether the perceived offensiveness of slurs survives when they are reported, by comparing Italian slurs and insults in base utterances (Y is an S), direct speech (X said: “Y is an S”), mixed quotation (X said that Y is “an S”), and indirect speech (X said that Y is an S). For all strategies, reporting decreases the perceived offensiveness without removing it. For slurs, but not insults, indirect speech is perceived as more offensive than direct speech. Our (...) hypothesis is that, because slurs constitute hate speech, speakers employ quotation marks to signal their dissociation from slur use. (shrink)
