“This shooting is a reminder of the enduring virulence of anti-Semitism,” said the president and chief executive of the Anti-Defamation League, Jonathan Greenblatt, in a statement. “It must serve as a call to action for us as a society to deal once and for all with this hate. People of all faiths should not have to live in fear of going to their house of worship. From Charleston to Pittsburgh to Oak Creek and from Christchurch to Sri Lanka, and now Poway, we need to say ‘enough is enough.’ Our leaders need to stand united against hate and address it both on social media and in our communities.”
