You only need to look around the world to see that race/colour has nothing to do with it. There have been plenty of black leaders around the world. There have been plenty of woman leaders around the world. And none of them have been wonderful leaders any more so than all the white men leaders.
Everyone needs to get over this idea of government being what it tries to tell us it is. And FFS stop looking for a fucking messiah. The last time one of those came along it ended in WW2.
