We can be a fickle bunch, us Aussies.

Our passions and opinions can change so quickly it's often hard to remember which side of which fence we sit on.

It seems we can change allegiances with ease.

A fortnight ago Glenn McGrath was a national hero.

In my mind he very much still is, and hopefully I'm not alone.

Our greatest fast bowler sent down almost 30,000 deliveries in Test matches alone, for 563 wickets, and bowled us to countless victories during a decorated career.

He inspired tens of thousands of young cricketers in Australia and has done his best to nurture the game overseas. If you're not a cricket fan you can ignore those statistics, but you can't ignore his work in the field of breast cancer treatment for the past seven years.

He and his late wife Jane McGrath founded the McGrath Foundation in 2008 following Jane's cancer diagnosis.

The foundation now has 102 specially-trained breast cancer care nurses employed around Australia and caters to 33,000 families being affected by the disease.

Glenn works tirelessly to raise awareness of breast cancer through the foundation and his ties with the sporting community.

Sounds like a pretty decent guy, right? But all of a sudden we have a huge portion of the country calling for his head - literally.

Photos surfaced last week of McGrath posing next to a number of dead animals during an African hunting safari in 2008.

The hunting trip was legal and licensed.

Shooting animals for sport is a polarising subject.

And while I'm not particularly fazed by the photos of McGrath, I can certainly understand why some people choose to be.

Everyone is entitled to their opinion and I respect most of them.

But some of the reaction to McGrath's hunting trip over the past week has been disgusting.

Much more disgusting than the photos themselves, no matter how you feel about the shooting of animals.

Threats of injury and even death have been directed towards McGrath, his family and reportedly even staff members of the McGrath Foundation.

Does shooting a buffalo equate to murdering a man's family?

Some deranged members of the public have called on others to cut support of the McGrath Foundation.

They want people to help bring down an organisation which helps 33,000 families dealing with breast cancer.

McGrath even issued an apology for his actions.

He didn't do anything illegal and surely his good actions massively outweigh his bad?

It's also unclear why this uproar is needed seven years after the fact.

Who felt the need to jump on these photos from 2008 and toss them back into the social media whirlpool to clearly tarnish a man's name?

McGrath has never hidden the fact he enjoys hunting animals.

And yes, shooting buffalo and elephants is the wrong thing to do.

But it astounds me how people can turn on him so quickly and so viciously.

And now people are attempting to drag Brett Lee into the furore.

Meanwhile, we have any number of footballers playing in the NRL who have been convicted of domestic assault, assault, drug dealing and other crimes.

The only thing most of those guys have contributed to society is a couple of hours' entertainment for a minority of the Australian public on a Friday night or Sunday afternoon.

It's fine to disagree with the shooting of animals.

But people should remember to put it in perspective before tweeting, Facebooking or speaking.
