Steve Sailer, the author of the UPI story I quoted previously, commented and pointed me to a much longer and more detailed essay he wrote for National Review in 1997 titled "Is Love Colorblind?". He addresses many of the issues and gives a lot of data and historical background, and I highly recommend it to anyone curious about the issue. A short excerpt:
Interracial marriage is growing steadily. From the 1960 to the 1990 Census, white - Asian married couples increased almost tenfold, while black - white couples quadrupled. The reasons are obvious: greater integration and the decline of white racism. More subtly, interracial marriages are increasingly recognized as epitomizing what our society values most in a marriage: the triumph of true love over convenience and prudence.Nor is it surprising that white - Asian marriages outnumber black - white marriages: the social distance between whites and Asians is now far smaller than the distance between blacks and whites. What's fascinating, however, is that in recent years a startling number of nonwhites -- especially Asian men and black women -- have become bitterly opposed to intermarriage.
This is a painful topic to explore honestly, so nobody does. Still, it's important because interracial marriages are a leading indicator of what life will be like in the even more diverse and integrated twenty-first century. Intermarriages show that integration can churn up unexpected racial conflicts by spotlighting enduring differences between the races.
For example, probably the most disastrous mistake Marcia Clark made in prosecuting O. J. Simpson was to complacently allow Johnny Cochran to pack the jury with black women. As a feminist, Mrs. Clark smugly assumed that all female jurors would identify with Nicole Simpson. She ignored pretrial research indicating that black women tended to see poor Nicole as The Enemy, one of those beautiful blondes who steal successful black men from their black first wives, and deserve whatever they get.
The heart of the problem for Asian men and black women is that intermarriage does not treat every sex/race combination equally: on average, it has offered black men and Asian women new opportunities for finding mates among whites, while exposing Asian men and black women to new competition from whites.
