Stefan Molyneux mentioned some telling statistics concerning the timing of the rapid increase in illegitimate births. This chart shows the percentage of illegitimate births, which have risen by an order of magnitude, from 4 percent in the 1940s and 1950s to 41 percent in 2010.
Notice the giant leap between 1960 and 1970. This cannot be entirely the result of feminism, but is likely a combination of a) the War on Poverty, b) the 1965 Immigration reform act, and c) feminism. The rise in illegitimacy is closely correlated with the changing racial demographics.
The situation is clearly not sustainable. Society will never be a functional brown equalitarian version of historical white American society. The concept is not even remotely credible given the observable evidence. This multiracial illegitimacy alone is sufficient to indicate why racial segregation is inevitable regardless of how anyone feels about it.
Homogeneous socities arise from heterogeneous societies because the latter are structurally inclined towards collapse. US society simply cannot survive in its current form; the stagnation and decline the USA has experienced to date is only beginning, as the effects of this 50-year destruction of the family are not even close to fully realized yet.
