SJS, I disagree with you on the McGrath issue. I think it's a very valid point to raise - not to demonize McGrath in the slightest, but to illustrate that a bowler who nobody in their right mind would have called a chucker actually breaches the old tolerance levels. It firstly demonstrates that perhaps the previous tolerance levels were inadequate, but also asks "If McGrath is doing this, what makes Murali such a disgusting cheat?"
I'm an Aussie supporter who, up to now, has believed that Murali was doing something that everybody else
wasn't, so what I've heard at this point (presuming it's not completely unrepresentative) has been a bit of an eye-opener. As to why Australians in particular (and I am certainly one) have such an issue with Murali, I would guess that it comes down to defensiveness about being from the country where he was called during that huge melodrama back in '96 and '99. And ego is a very powerful thing.
Much of what we've seen in some threads makes very little sense to me, but I would argue that there's not a complete lack of objectivity about this issue on these forums (on BOTH sides) - just that it was predictable that things would "get ugly" for some after some of the ramifications of this report became known.
I think somebody earlier (I can't remember who) already put it in the context of Elizabeth Kubler-Ross's five stages of the loss process - only maybe we've skipped "bargaining" and gone straight from "denial" to "anger" and "despair".
Anyhow, your mileage may vary.
