I watched the entire match including the observations made by, "only" Johnny Wilkinson, Sir Clive Woodward and Lawrence Dallaglio and I guess I am only repeating what they said. Did you see it ? The referee could have been Irish, Scottish or any nationality really, they just said he was the Welsh referee that missed a clear red card. The referee admitted he did not see it, to the amazement of myself and the three ex.rugby professionaals above as he had a clear view only a few metres away. You cannot always keep your eye on the ball, can you ? The TMO came in to assist. I do not think the above rugby players are bigots either. The relationship between the TMO and the referee worked here.
Wales were offside in their winning try against Australia. The offside line was in the wrong place and the TMO did not review it correctly. The TMO was blasted, and he was openly spoken about to be from New Zealand. You may have watched that game to conclude "that not everyone is a bigot"
No need to apologise Doreen and no this is not a lecture !
