Sen. Cory Booker reminded a lot of people at the Democratic National Convention Monday night of Barack Obama circa 2004. He was one of the few speakers to show genuine enthusiasm for Hillary Clinton and preached a message of unity to a deeply divided audience, quoting a favorite African saying: “If you want to go fast, go alone, but if you want to go far, go together.”

Members of Tuesday’s Black Resistance March in Philadelphia didn’t go fast, but they did go together — at least until an organizer of the protest ordered media covering the demonstration to rearrange themselves by race.

Black Lives Matter protesters in Boston drew up a helpful list of white people’s roles and responsibilities a couple of years back, and those rules seem to remain in effect, including guidance to follow the direction of black leadership.

For what it’s worth, whites aren’t always sent to the back of the march; at demonstrations in Boston in 2014, white allies were ordered to the front lines to do their part when arrests began:

Democracy Spring, who staged the sit-in yesterday blocking the delegates’ entrance to the convention hall before spilling over a tiny border wall that just got higher, were happy to make way for the Black Resistance March.

That’s a convenient excuse to skip protesting for a day to catch the epic “Bernstock” music festival.
