SeaJayPea - if people want to find an excuse for their team losing, they will - this is simply another example of that.
The authorities decided on the referee based on his experience, competence and professionalism, and correctly decided that his lineage is not an issue, and anyone who wishes to make it an issue is simply biased.
Had it not been the lineage of the referee, those people who lack in sufficient objectivity and who allow emotion to overcome the appliance of rules, would have found some other reason for the deicison - the referee parts his hair on the right, he is left-handed, the sun was / wasn't in hie eyes ... the list goes on.
The decision was correctly applied, the game is over. That's it.
