If the 'rights' that this country was practically founded with don't need to be 'rights' -- then you should propose just eliminating the constitution in general. Why do we need a 'right' to be free of unreasonable search and seizures? Why does the freedom of speech have to be a right? I'm sure what's left of the government will act in the best interest of the entire country. And surely all the guns will just cease to exist after our right to legally bear them is repealed. Gangsters, teenage boys, drug dealers, they will all happily turn in their guns and promise not to get any more.
