Blackford does a good job explaining how the rise of the internet has made self-expression much more risky, since any violation of supposed norms can result in the formation of an internet mob in hours.

CHOICE

Anyone who has felt chills after watching a news story about crazy SJWs on a college campus or witnessing a P.C. mob on Twitter should read this book for a more nuanced understanding of political correctness and the 1st Amendment, in general.

Ultimately, Blackford enjoins readers to 'take a stand, as loudly as [they] dare, for liberal values and for freedom'. Noting that most of us are happy to entertain and to venture a much greater range of views and opinions in private than we are in public, he suggests that we should, to the extent that we can, be courageous in doing so publicly, for the sake of 'true' liberal principles and values...Blackford's book exemplifies how things might be if only we would all stop shouting at one another and learn to listen.

Ceridwen Spark, Australian Book Review

If we are to have a coherent commitment to free speech, our conception of that value should allow for it to be applied consistently, whether involving controversial expressions by either friends or enemies, or the expression of either popular or unpopular ideas. The Tyranny of Opinion is a valuable resource in helping us to think these problems through, and I'd encourage you to read it.

Jacques Rousseau, Synapses

On that (literary) point, Blackford has a beautiful, calm, civil voice. He writes gorgeously, guiding the reader through a great deal of material with expertise and, sometimes, élan. It is a lesson in how to argue, and how to think. The Tyranny of Opinion: Conformity and the Future of Liberalism is an exceptional book. Anyone who engages in political debate should read it.

Quillette

A masterpiece. This should be required reading for every university professor.
