Moms Demand Action, a gun-control group backed by former New York City mayor Michael Bloomberg, has launched an advertising campaign asking retail chains to refuse service to shoppers who openly carry assault rifles into their establishments. In response to retailer claims that doing that would violate their customers’ civil liberties, the ads point out that retailers have had no qualms about enforcing a ban on shirtless shoppers, eating ice cream cones and skateboarding. This series of ads targets Kroger, the largest grocery chain in the U.S. So far, nearly a half dozen national restaurants and stores have reversed course in response to Moms Demand Action advertising and publicity campaign. No word yet from Kroger.
