I'm saying that I accept the science says that the IQ scores differ among the races, uncomfortable though I am with that fact.

Whether that means that certain races are "less intelligent," isn't a scientific question, because IQ tests only measure fluid and crystalized intelligence commonly referred to as reasoning and problem solving ability.
Science also shows a high correlation between IQ and economic success.
Does a high IQ definitely set you up for more success down the road – be it in terms of career advancement or higher salaries? The answer, essentially, is yes, according to researchers.

Does a child’s high IQ set them up for career or financial success down the road? According to psychologist John Antonakis, the answer is essentially yes.
″[IQ is] the single most important predictor of work success,” Antonakis, a professor of organizational behavior at Switzerland’s University of Lausanne who focuses on leadership and management research, tells CNBC Make It. “It’s a very robust and very reliable predictor.”
In 2012, Vanderbilt University psychology researchers found that people with higher IQs tend to earn higher incomes, on average, than those with lower IQs. Past studies have also shown that high IQs are comparably reliable in predicting academic success, job performance, career potential and creativity.
I don't believe that this gap is set in stone. I believe that there are likely cultural and/or nutritional causes for it. If we are to address the gap and find ways to narrow it, we would first have to recognize it, and I understand why that is difficult. From the Brookings Institute:
Narrowing the test score gap would require continuous effort by both blacks and whites, and it would probably take more than one generation. But we think it can be done. This conviction rests on three facts. First, black-white differences in academic achievement have narrowed since 1970. The National Assessment of Educational Progress (NAEP) data on 17-year-olds show that the reading gap narrowed more than two-fifths between 1971 and 1994. The math gap has also narrowed, though not as much. Five major national surveys of high school seniors conducted since 1965 show the same trend. So do surveys of younger students. The gap narrowed because black children’s scores rose, not because white children’s scores fell.
Second, even IQ scores clearly respond to changes in the environment. IQ scores, for example, have risen dramatically throughout the world since the 1930s. In America, 82 percent of those who took the Stanford-Binet test in 1978 scored above the 1932 average for individuals of the same age. The average black did about as well on the Stanford-Binet test in 1978 as the average white did in 1932.
Third, when black or mixed-race children are raised in white rather than black homes, their pre-adolescent test scores rise dramatically. These adoptees’ scores seem to fall in adolescence, but this could easily be because their social and cultural environment comes to resemble that of other black teenagers.
