Giving PetitionOnline.com Users the Ability to Sign AGAINST any Petition

If you've spent even a short amount of time browsing PetitionOnline.com, I'm sure you've come across some petition or another that you find offensive, misinformed, generally idiotic or anything else, and wished you could show your opposition, but to do so would require you to actually sign the petition or create an entirely new petition.

I propose that PetitionOnline.com give its users the ability to sign -against- any petition, allowing a more accurate view of how supported that petition is and enhancing the level of free speech granted by this service. This will also cut down on the number of petitions being created, as responses from people that don't share the opinions of the petitioner would be contained within that petition.
