Re: United Earth? No Thanks.
The insistence that nations must possess that sovereignty is to insist that a national government must be free to act against the general interest of humanity, that a select portion of humanity must have the right to refuse to abide by the majority rule of humanity. Why would this be desirable? Again and again, it always comes down to the visceral hate for the very idea that other, lower forms of humanity should have the same human rights as "US."
Quoted for truth.
Democratic socialism is the hope of human freedom.
