On the evening of June 10, in the midst of an impromptu desecration festival in Portsmouth, Virginia, the statue of a Confederate soldier was yanked off its pedestal and crowned the unfortunate Chris Green, who stood underneath. Green, now in a medically induced coma, coded twice on the way to the hospital. He may not survive. Erasing the past is a dangerous business. It has been since the communists got involved in rewriting history a century ago.
