"Moral Monday" spreads outside of NC

The protests in Ferguson, MO have taken on the "Moral Monday" label pioneered by the protestors in Raleigh.  This from AP:

Organizers of the four-day Ferguson October protests dubbed the day "Moral Monday" and committed acts of civil disobedience across the St. Louis region. Some protesters used a bullhorn to read the names of people killed by police nationwide. Christian, Jewish and Muslim clergy members - some of whom were among the first arrested - led a prayer service before marching to the station two blocks away.

"My faith compels me to be here," Bishop Wayne Smith of the Episcopal Diocese of Missouri said outside Ferguson police headquarters. "I want to show solidarity, and call attention to the structural racism of St. Louis."

Protesters were met by about 40 officers in riot gear. Several clergy members approached individual officers and asked them to "repent" for Brown's killing and other acts of violence. Some officers engaged the protesters, while others ignored the efforts.

"My heart feels that this has been going on too long," Ferguson officer Ray Nabzdyk told the clergy. "We all stand in fault because we didn't address this."

Why do they adopt that label?  Will it spread further?  Certainly something that bears watching, especially since we have a week on the Religious Left coming up.
