We cannot change other people's minds. But we must try to help people see the implications of their decision. One candidate is sane and experienced, has a detailed grasp of policy, and knows world leaders. The other is gaspingly ignorant, shoots from the hip, and is openly contemptuous toward women and minorities.
Structurally, something similar seems to be happening in reverse. That is, instead of a situation in which structural disparity results from some sectors failing to develop while other sectors raced ahead, we now are fostering structural disparities owing to sectors that are falling backwards, out of the modern (or post-modern) world.
