In the wake of this week’s terrorist bombings in Brussels and heated anti-Muslim rhetoric in the U.S. presidential race, we read with interest Beenish Ahmed’s NPR essay, Learning — And Unlearning — To Be An 'Ambassador' For Islam. We invited Ahmed to speak more about her experience as a Muslim in America, trying to appear nonthreatening to an increasingly anxious American public.

When it comes to promises made by social movements, human rights scholar Rebecca Hamilton has heard it all. “Share this Facebook link and you can save the life of a child in Uganda. Wear this bracelet and you can bring peace to Darfur,” she recalls. “The problem is most of the time, it’s simply not true that doing a low-cost action can be very high value to somebody somewhere else.”

MacArthur “genius” award winner Corinne Dufka was a photojournalist for Reuters, covering armed conflicts in 17 nations. But inside a hotel room in Rwanda, she had an “epiphany” that compelled her to leave photojournalism at the height of her career. Dufka discusses what drives her to champion the rights of the marginalized, whether inside a psych ward in San Francisco, at a rain-soaked refugee crossing in the Democratic Republic of the Congo, or in a Bosnian battlefield, where Dufka herself was severely injured by a landmine. Dufka is now a researcher for Human Rights Watch.
