government doesn't exist to think of the people's opinion, it exists to protect the people.
This isn't a true democracy, and I'm damn happy that it isn't. If it was all of the idiots of the country would have there way, they probably out number the thinking people anyway.
We elect officials that we think best serve the people's interests, if we're wrong that's our problem, no use complaining about it just do a better job at voting for the right people. And to those who would say to this that they are not old enough to vote shut the forget up. If you are not old enough to vote than you aren't old enough to bitch about something that you can't change.
Also, I'm pretty sure an internet petition holds little weight in any real situation. Considering any number of the signatures can be from people who are not registered voters, it makes those signatures pretty much irrelevant. It's only real use is to sway peoples emotions, and this is a pretty black and white matter, no real on the fence position exists for this matter.
