Yes, people might not agree on what's best. But I don't think anyone feels like they can surely get away with murder. That means for them to decide to kill someone, they themselves are also sacrificing their own future. People will only do that for a cause that they truly care about. And while people are divided, on almost all issues they don't hate the other side enough that they'd be willing to sacrifice themselves for the cause. You need to do something uniquely unpopular for receiving that intensity of hate. Also, it seems like despite the divide, most people agree on their hatred for insurance companies?
