This is a significant volume in the hate speech literature. It offers a powerful counter-point to recent works advocating hate speech bans, most notably that of Jeremy Waldron. It will definitely be of interest to anyone working in the political or legal philosophy of freedom of expression. Beyond the immediate academic audience, this is still an important work. It should be accessible enough to readers who are used to academic texts, and it presents a lot of the legal background to the issue clearly. The book's major strength is in presenting a defence of freedom of expression that is firmly rooted in the important, though abstract, discussion of rights and citizenship, but at the same time gives proper credence to real-world factors that shape legal regimes. It contributes not only an important critique of some prominent positions on freedom of expression, but also a distinct methodological approach to the problem.
