I can understand that view, but in the UK racism exists, as it does in every country I have visited in my lifetime. Although can't say I've travelled all over the world, I have travelled extensively in Europe, in North America and the Middle East and everywhere I've been I have come across racism in and between various ethnic and racial groups. From almost fairly benign "I'm better than you" type encounters, to institutional and systemic racism perpetrated daily.
I don't know what we can do about eradicating it completely, when every single person, is or has the potential for racism within them. I don't believe those who say they haven't a racist bone in their body, or words to that effect. Politicians of course realize that racist tendencies are present in everyone and they can play one off against another, as they do with social groups, and as we've seen many times this 'political trick' works, almost every time, either as a distraction or to undermine opponents.
What does worry me as a 70+ year old is the constant harping back, be it either for some who yearn for the so called 'sun-lit uplands' of the past to return, or for some that seem to believe the present needs to be punished for the sins of the past. There is so much pain and inequality still occurring which has a basis in racism; take slavery, that is the modern-day version, where very young children work in 'sweat shops' all over the world to eke out a living and to provide cheap clothing for those usually in better off countries. I wonder how many of those protesting this weekend were wearing such 'tainted' goods?
The current mood has been sparked by what has happened in America, but as many have pointed out such actions can and have occurred all over the world and not just in western countries. Frontline Policing anywhere is a dangerous job and should be undertaken only by those who meet the highest standards of humanity and personal restraint and commitment and who have undertaken vigorous training and testing. Unfortunately Frontline Policing (in particular) as with some other occupations identified under the impact of the Covid-19 pandemic are not properly personally protected, trained, or necessarily paid according to the service they provide, or should provide, for the public.
