This is a revised version of a talk delivered at the ALA 2019 Annual Conference on June 22, 2019, in the discussion group “Hate Speech and Libraries,” sponsored by the Social Responsibilities Round Table (SRRT) of ALA. Tom Twiss is co-chair of the International Responsibilities Task Force of SRRT and a member of the SRRT Action Council. Views expressed in this commentary reflect the general position articulated by SRRT Action Council in its August 2018 “Statement on Hate Speech and Libraries.” However, neither this commentary nor the talk on which it was based was endorsed by SRRT or its Action Council.
