An excellent and penetrating review of self-censorship by Yale University Press and the once-respected Index on Censorship by Ophelia Benson. Several good comments to check out, too.
The reality is that a few people can always punish someone for an imagined offense; there is no way to rule that out in advance without giving up doing anything. We can’t afford to do that. We can’t afford to get so frantic with fear of remote, potential, unlikely possibilities of danger that we stop doing things we have good reasons to do.
The more of us who stand up against censorship, the less power we grant to those who would shut us up.
