I find that quite hard to believe, as I don't see any visual distinction between Brits, Ashkenazi Jews, Irish (unless ginger), northern Italians and Poles. Southern nations could be distinguished (e.g. southern Italians, Spaniards, Greeks), in that case it could have been racism (e.g. in the US they still consider "Hispanics" a different race, although I don't).
