I cannot help but notice that the Aussie supporters here fall into two distinct groups.
A seemingly realistic group that accept that Australia can't win everything forever and realise that even though their team is 2 - 1 down they are contributing to the best test series in history, and seem to be able to cope with defeat admirably.
And the other group who look for excuses, umpiring decisions, substitutions, injuries and anything else they can dream up. One minute they will be posting "We are going to win this" when a seemingly unrealistic win looks in sight, the next they are calling for heads to roll when narrowly defeated. They fail to mention anything else, and they are beginning to remind me of aggrieved soccer fans, with accusations of cheating, bad decisions (that only go against them).
This arrogance is probably born out of a recent history of them winning everything. They simply don't know how to take defeat with grace, much like their captain. Uproar and adulation one minute, anger and recriminations the next. I found it quite fun to read the posts relating to the ashes match as the events unfolded.
Alas, there are many fans from many nations that taste defeat in many sports, but none so fun to watch as Aussie fans whinging about cricket defeats.
