Example of racism stemming from ignorance.
In the UK black kids are very more likely than white kids to do badly in school, and more likely to be remanded in custody.
So you might conclude from this things such as, black kids are inherently badly behaved, other things you can probably imagine.
Yet when you look at the statistics, you notice that black kids are more likely to be from a poor family, and more likely to be from a single parent family.
And when you compare like for like, e.g. poor white kids with poor black kids, or white kids from single parent families with black kids from single parent families, things even out, or there is much less difference.
And even when there is still a difference, race is still not going to be the cause of that difference There will be a third factor, then a fourth, then a fifth.
For instance, poor white kids do worse in school than poor black kids. No-one would say thats "because they're white".
But when people they think they see the opposite they will quite possibly say its "because they're black".
The problem with this ignorance of the facts is that it prevents the root causes of these kinds of problems from being tackled.
It's a unfunny irony that a racist attitude helps lock in place the very situations that contribute toward people being racist.
