BLM and Thousand Currents The original organizers (Patrisse Khan-Cullors, Opal Tometi and Alicia Garza) of BLM are self described trained marxists. The Thousand Currents, who underwrites financially for BLM, is headed by Susan Rosenberg who is a convicted felon who participated in bombing buildings in the Northeast and Washington, DC. Just about tells you about BLM. They are not for blacks at all. They are marxists from top to bottom.
