Read just the first chapter of John Stuart Mill's "On Liberty" (free via Project Gutenberg etc) and tell me that he didn't have his finger precisely on the pulse — in the 1850s — of the root cause of the authoritarian war for majoritarian supremacy that we're witnessing today. Censorship, the compelled worship of an ever-shifting orthodoxy, the construction and desecration of idols before the temple of consensus— it's all the same thing, arising from the same source, and awaiting a similar solution. In times of trouble, we should look more to our history. 

Read your Mill, brothers.
