White supremacists marched with torches during a rally in Charlottesville, Va.Credit...Edu Bayer for The New York Times
Fire has historically been used in battle, and as a fear tactic. Take the Great Fire of London in 1666, which destroyed thousands upon thousands of homes, churches, and businesses. While that fire may have been an accident, it's a testament to the destructive power of fire.
There are many things, passive and active, that white supremacists could accomplish with such tiki torches, including burning people of color in direct combat. Considering the nature of white supremacy, I'm surprised I have not seen such accounts of violence on the news.
