The inaugural Eradicate Hate Summit was a truly impressive gathering of leaders dedicated to finding lasting and effective solutions to violent extremism. I was particularly moved by the prominence given to survivors and family members of victims of hate and violence throughout the event. Their stories and those of so many others must be at the center of what we do and why we do it.
