Agree with you Ronaldo. Anything is possible and as impossible as things are, someone needs to start somewhere. If Martin Luther never bothered maybe it would be longer. Although I think it also shows education matters a lot.
It amazes me how much we loose sight of issues. Obama won the presidential election of USA which arguably is the most ethnic diverse continent in the world that means every vote would have mattered whether black, white, native Indians, Cubans, Jews, Italians ...you name it and American history speaks for itself in that sense. That achievement can only inspire if we dedicate ourselves to what we do in our daily lives. Obama cannot wave the magic wand, we can by contributing our own quota that is where the inspiration lies.
