Would you explain to me please
The brief summary that I posted yesterday ought to suffice.
But to elucidate further, the 'tribalism' that exists between different nations, such as Scots, English, Americans, etc, signifies no difference in equality. For sure there is is often a xenophobic mentality, such as "our nation is the best", but that is just bluff and bluster. Unless the person expressing it, genuinely believes it. Then it is delusional. It is racism, all the same, just that there is no existential structural inequality.
Whereas the structural inequality that exists, say in the Met Police is endemic. It is so endemic that the average plod is unaware of it. They are socialised into that inequality, but practise it and reinforce it none the less. The same applies to the UK society in general. Those unfortunate to be born to racist parents are socialised into that racism from an early age. They internalise it and think it is a human nature to be prejudiced towards foreigners.
Then there are those that try to propagate racism by creating hatred and division in society. They're just racist thugs. I very much suspect that if it was not racism that they use to propagate hatred, they'd adopt some other 'difference' to justify their behaviour.
Both sorts, the xenophobic sort and the structural inequality sort, can be eradicated through education. But sometimes, in case of more overt racism, legislation is required, whether that be equality legislation or punishment for racial hatred.
Sometimes, in case of structural inequality, policies can be introduced to combat that structural inequality, e.g. Kick it out policy in football, so that minority candidates get an equal opportunity. The proponents of structural inequality probably even believe that they are not overtly racist, for example the recent episode of Gregg Clarke.
I'd suggest that, in the main, the proponents of structural inequality are totally unaware of that structural inequality, such is its pervasiveness. . Whereas the victims of that structural inequality understand that so many opportunities are denied to them simply because of the colour of the skin.
Sadly, having taken up a few precious minutes explaining that, I doubt somehow that you'll even bother reading it all.
