The city of Boston is launching a poster campaign to fight Islamophobia by encouraging bystanders to intervene, in a nonconfrontational way, if they witness anti-Muslim harassment.

Starting Monday, the city began installing 50 posters around the city with advice on what to do if you see Islamophobic behaviour. The posters recommend sitting by a victim of harassment and talking with them about a neutral subject while ignoring the harasser.

 THE ‘HOW TO’ GUIDE PUBLISHED ON TUMBLR IS BEING USED BY CITIES TO RAISE AWARENESS OF ABUSE

The campaign is based on a step-by-step guide developed by Marie-Shirine Yener in response to Islamophobia in France. The guide first appeared on Tumblr and has now been adopted by a number of cities addressing this form of discrimination.
