Cargo744, Edmund Burke once said: ""The only thing necessary for the triumph of evil is for good men to do nothing.", There isn't much that many of us can do alone, but what we can do is try to be heard, to spread the word.
What the likes of Alan Joyce and his ilk spread is a virus, a disease, their words are designed to poison and weaken us to the point where we cannot see past them, something like this petition allows for people to spread the truth, to get it out there, like an anti-virus or vaccine, it allows people to build an immunity via truth.
Petitions, emails, this is how things like this spread, it's easy to say "Why bother, it won't do anything", it's a lot harder to instil some faith and allow yourself to hope that maybe by signing and getting others to sign it'll eventually spread to the right people and convince them to get up and do something. Each person who signs it and spreads it can get a few more, who get a few more, and a few more like tendrils, but people like yourself block it and hinder it.
1000 might not be many, 2000 still isn't a lot but if everyone signs it and shares it eventually they have to take notice, it emboldens people like Nick Xenophon to continue their causes and push harder and do the right thing!
Maybe I'm naive to a certain degree but sitting back and doing nothing will achieve precisely that, nothing.
