Should we be Building or Dismantling Echo Chambers?

Sami Pihlstrom argues that, for principled reasons, we have a duty not to listen to racists. Although this stance can seem admirable, I wony that by cutting itself off from evidence, a refusal to listen leaves wrongfully accused persons no means of exonerating themselves. Moreover, given that concepts like racism now encompass beliefs and acts that many rightly consider sensible, a policy of silence risks dismissing implausibly large numbers of people as immoral. Stressing that listening is not acquiescing, I urge Pihlstrom to think more carefully about the consequences of his stance, especially since it would increase the likelihood of conflict.
