It is nothing short of horrifying, but sadly also completely unsurprising, to see an ACLU lawyer proclaim his devotion to “stopping the circulation of [a] book” because he regards its ideas as wrong and dangerous. There are, always have been, and always will be people who want to stop books from being circulated: by banning them, burning them, pressuring publishing houses to rescind publishing contracts or demanding corporations refuse to sell them. But why would someone with such censorious attitudes, with a goal of suppressing ideas with which they disagree, choose to go to work for the ACLU of all places?
