Callie Crossley, host of WGBH News’ Under The Radar spoke with Boston Public Radio on Friday about Rob Bliss, a white man who was harassed for holding a "Black Lives Matter" sign in Harrison, Ark., a town known for its history of white supremacy and KKK affiliations.

"You will note that sometimes the people opposed to [racial justice] protesters aim their anger more fiercely at the protestors who are not of color, because they feel like they're betraying something," Crossley said.
