I understand your point but again you can point him out using a visual. If you are doing this over a headset its a lot harder.
But I agree surely people are aware that the words used last night could be seen as racist.
Him is quite hard to identify if there is a group of people and you aren't going to point them out. I don't think its right, but people are usually identified by their differences if you don't know someones name. how are you going to point someone out? the tall guy, the short guy, the bald guy...
