Lest my last posting on father and sons lead anyone think that ExC has gone soft, let me replay one of my fun thought experiments. I find that these clear away a lot of mental rubbish.
On five separate islands, with similar natural resources, deposit 10,000 people each.
On one island, Whites, an another Blacks, on others Hispanics, Asians and, as a control, so to speak,
a population that mirrors the current multiracial demographics of the US.
Provide each of the five islands with the same resources and, to start out, similar governments and then...watch what happens.
