Another turnaround

Half Sigma linked to this piece by Eric Posner pointing out that what we think of as the "American" absolutist attitude to free speech is really only half a century old.

I bring it up not to comment on Posner's argument about the desirability of censorship of hate speech, or Half Sigma's warning about the likelihood of a liberal-majority supreme court outlawing swathes of HBD and other blogging, but simply, like the sexual habits of 1970s DJs, as an example of how quickly the commonplace can become unthinkable, and the unthinkable commonplace.
