On average black people have a lower IQ so it would be called racist and infringing peoples rights is stupid how about if you have low IQ you don't have the right to free speech I don't think so
In the UK, where you're from, African immigrants and their children do better in school and are more likely to go on to uni than Brits, Asians, and West Indians.
In the US, Nigerians score 15pts higher on IQ tests than average whites.
