 As is the case with pornography and silencing, the details of the mechanisms that sustain this type of silencing, along with what particular type of silencing racist hate speech results in, are subject to dispute. But, just like in the pornography debate, the plausibility of the silencing argument lies partly in how it reframes the overall question surrounding regulation. Rather than simply being a source of harm that merely infringes on the equality rights of its targets, if hate speech silences then it also infringes on the speech rights of its targets (West, 2012). As a result, it is not simply a question of balancing the speech rights of hate speakers against the wellbeing of their targets, but of competing claims to (substantive, and not just formal) freedom of expression. And given the importance that most liberal democracies place on freedom of expression, the challenge presented from hate speech is of central importance. For this reason, the silencing question is one of the most disputed aspects of hate speech and has generated great attention.
