It's a time of tension in America as civil rights activists push back against marches from the Klu Klux Klan, white supremacists and neo-Nazi groups, people who fly the Nazi flag alongside the American flag. The marches have resulted in violence with both sides saying they were defending themselves from the other. In Charlottesville, Virginia, violence broke out resulting in the death of Heather Heyer, a counter-protestor, who was hit by a man driving a Dodge Challenger.
