This gif was flying around FaceBook, from the Chicago events last night at UIC, where Trump got shut out. Notice that, behind the guy whose sign gets torn up is a guy in glasses, holding aloft a kufiya-patterned scarf, with the collars of the Palestinian flag on either end. Behind him someone is holding is a Mexican flag. On the left, you can spot a woman wearing a cap with "African" colors. The protests against Trump were an occasion for the mobilizing of Muslims, Arabs, Hispanics and blacks, with identity symbols much in evidence. But photos and video footage of the protests also show that it was very much a coalition of people who came out, a multi-racial, multi-ethnic, multi-varied coalition.
I wasn't surprised to see video footage of protesters wearing kufiyas. Below are screen shots of two, that I found on this broadcast. I'm sure there were more.
