To the editor:

Fifty people are dead at the hands of a terrorist in New Zealand, and what have we learned? Words do indeed matter.

While expressing condolences, President Trump once again failed to address the underlying cause of the violence. The largest proportion of these kinds of killings are committed by white nationalists, not Muslims and immigrants. Yet the president insisted Friday that white nationalism is not a rising threat, despite the report that the suspected gunman behind the two mosque shootings wrote in a manifesto that he supported Trump “as a symbol of renewed white identity and common purpose.”

The question remains: Why won’t Trump forcefully denounce white supremacy?

While Trump may not be the direct cause of what happened, his anti-immigrant rhetoric incites division and fear. This in turn enables, emboldens and empowers hatred—a hatred that inevitably leads to violence. Trump is at least in part responsible.

Moreover, historians will write that those who refuse to stand up and hold Trump accountable for his bigoted rhetoric, including many Republicans in Congress, are complicit.
