The Summit offers a unique opportunity to confront the corrosive influence of bigotry and hatred in our society. In order for us to address these challenges, we first must acknowledge their painful and destructive impact in our communities and in our country. I am grateful to serve as a Global Advisor to this timely and powerful initiative.
