We have seen it over the years...after WW2 the Japanese/Americans were shunned...now, regardless the Arab decent has trouble. When I lived in South France I too got a taste of it. I lived between two villages...one loved me for being American and most businesses in the other hated me. One place wouldn't let me purchase anything in their store. My French wasn't great but I tried. Some patrons in the store even translated to the sales person for me and they still wouldn't help me.
