JcD, could we have backup statistics please? Emotionally I want to agree most of the way, but...Certainly many of the law students I teach at London South Bank University are black (Afro-Carribean), but at a guess I would say more black male than female. Some are excellent and some not so. I would however be quite surprised if: -

"Black African males are amongst the most highly qualified of our ex students" - at least if by that you imply that statistically Black African males are more prevalent (apart from WASPS) than any other grouping among the higher percentile markings in academic achievement.

This is not a supposition on my part, but an observation of actual classwork grades amongs those whose work I have marked.

I think I remember seeing some GCSE grade statistics with rankings, and my recollection (which may be faulty) is that the 4 top slots were: -

Sino-Japanese, female
Sino-Japanese, male
Asian, Female
Asian, Male

with Afro-Carribean, Male, at the bottom. The hypothesis was, I think, adverse cultural influence and expectation, but I'm not sure.

Once (and not until) you have the bare facts you can start to look for reasons, and maybe even cures (if you don't like the facts).

And, shouters, please could we stop shouting? The Mudcat may possibly be the only place in the world where we could have an informed and temperate discussion. You may remember that Professor Eysenck produced some IQ statistics that purported to show a correlation between race and IQ. I don't remember the outcome of the discussion that resulted, nor do I remember how the nature/nurture artefact was removed from the data, but inertial data must surely be necessary.

For example (I don't have the root data) I am pretty sure that the diagnosed rate of incidence of schizophrenia is several times higer in black males than white - but at the moment we have (I think) no idea why. It might be prejudice in the diagnosticians, it might be a causative factor in local conditions, it might be genetic, we don't know. Conversely, sickle cell anaemia is restricted to the Afro-Carribean population and the reason is genetic.

If DH wants to make a case, he must produce a scientific hypothesis and then it must be tested. Conversely, if we want to say (for example) that one category of persons is as able as another, then we too must produce hypothesis and test.

If we want, however, to say that people should be treated equally despite possession of different ability, then that is a moral judgement, and we know it breaks down at the limit, for we generally accept that we may detain on mental health grounds those likely to be a danger to themselves or others.

The issue with the song is that it condemns for no reason other than race. That, I think, may be hard to justify.
