I odn't think it is racial. I'm a Palestine supporter too, i housed Kazakh refugees recently, my mother housed Georgians, and had my very catholic, conservative family do the same in the 2000s. They aren't caucasians, and are ethnically close to Syrian (turkomongols i guess?). But they are Christians, and Coptics do have a really good reputation in France (or at least in my part of France). It has everything to do with how you dress, your accent, and how the media portrayed you in the last 10 years.

Maybe we have different definitions of racism. In my view one is racist when considers a particular ethnicity superior to another.
