There is such a term - a man of the universe. To become one is both extremely simple and complicated too, because in order to be one it requires more then just passports and visa stamps, but strong feeling for freedom and belonging to the whole human race. If you are confident that state borders are just bent lines on maps, if you are sure that nationality doesn't designate a humans fate but only underlines his diversity. If you are open-hearted and looking forward to making the whole planet Earth one welcoming and hospitable home for all then you really do deserve to be called a man of the universe.
Though borders still exist, let chauvinism and nationalism fade away, the sooner the better, however in this community we can read this world like a book - for all and every single one out there. Dreaming to see such a world without borders? You are very welcome here to join others who share this simple view just like you do, that borders exist only in limited human minds, which just have to be whipped out from it in order not to appear ever again, because there just won't any good reason for them to emerge. All of that is just to see a world without borders, so let's start right now by living in a world without such borders in our minds!
