After Buffalo shooting, experts question whether America can face its far-right extremism problem

The rise of far-right extremism in America is under the spotlight following a mass shooting in Buffalo, New York.

Within the pages of the alleged Buffalo shooter's plan to attack a Buffalo, New York supermarket, he described the radical ideals he said he cultivated on the internet.

It included racist and antisemitic rants reminiscent of the sentiments espoused by shooters who committed similar atrocities in El Paso, Texas, and Charleston, North Carolina, in recent years according to an ABC News review of the document.

Federal security agencies have increasingly sounded the alarm on white supremacists and other far-right-wing extremists as a "significant domestic terrorism threat."

However, experts on hate in the U.S. said this most recent mass shooting highlights how little the country has done in reckoning with the growing danger of white supremacy in this country.
