Cambridge Police responded on Wednesday when stickers saying "It's okay to be white" were found in public spaces around the city. The Boston Globe reports the signs were promoted by anonymous trolls on an online, far-right message board called 4chan.

Cambridge Police officers used knives to scrape off dozens of stickers on utility poles and common spaces in the areas of Harvard Square and Cambridge Common.

The slogans were also found on fliers on college campuses at Tulane University in New Orleans and the University of Alberta in Canada, as well as in Rocky River, Ohio. The Washington Post reported fliers with the same slogan at a Maryland High School in Silver Spring.

A set of six directions for sharing the message originated on a 4chan message board, guiding them to print out "uniform posters" while wearing a "silly halloween costume for anonymity, nobody will think twice because it's halloween."

The sixth step -- the apparent goal -- says "normies realize that leftists & journalists hate white people, so they turn on them."

The move did spark a flurry of dialogue online. Some Twitter users and students interviewed defended the slogan as a simple statement while others said it was being used as a divisive tool.
