A telling point halfway down:
Recently, a popular stress on cultural identity, has worked to apply fresh paint on racial boundaries.
This reminds me of an article I read recently. A argument against inter-racial relationships, by a mixed-race American who married a white woman, is surely worth a read. Dell Gines post (found via Clive Davis and Booker Rising) asserts that since the pool of eligible black males has decreased in the USA due to social problems within those communities, if a white woman dates/marries one such eligible black man, she is reducing that pool even further. Black women are of course free to date white guys, but in both cases, the end result is the decrease of the black community. The erosion of the black community is a negative effect of all this.
My response is to reiterate that cultures are not fixed. They change and evolve over the generations. Black culture is certainly to be respected, but can and should it be preserved? (The same, of course, may be asked of white culture). The answer to all these questions is “probably not!” Even if the insidious eugenics proposed by Gines were employed, and a black racial purity was preserved in the USA, the black culture itself would change anyway. So why not accept this, and let black and white cultures merge with each other? As the author Hanif Kureishi suggests, multiculturalism is the idea that “purity is incestuous”. That cultures change into something else is not necessarily a cause for concern.
