Recently I attended a diversity workshop at my work place, I heard this word"people of colour" there. I just did not understand to whom it was reffered to,Middle easterns?Orientals?or African-Americans? I raised the issue there but I didn't get my answer. My impression is the word "colour" is an indication of paying attention to the people's skin colour instead of their ethnicity or their cultural background. I recommend the word "decent" e.g. Italian decent; even if we simply mention the name of the people's original country or continent e.g. Iranian, Asian it will be the first step taken to ignore people's skin colour and learn more about existing different ethnicities.I totally agree with not using the word "colour".
