I think Biden might have pulled back to 32,000 feet and defined this atmosphere, in which racism and ethnocentrism are parts, as our greatest threat. Terrorism brings certain things to mind and narrows the definition. It’s the wrong word. This is an atmosphere of people unwilling to compromise, live amongst each other or stand for ethics. Violence is the fallback. Racism is one element but so is Christian nationalism, misogyny, demographic decline, opioid addiction, cultural isolation, and depression. It’s a mess that needs a bigger box than racism.
