I want to understand more. I'm reading Reni Eddo-Lodge. It's helpful to understand her frustration with the protestations of 'colour-blindness' from white people as tantamount to saying 'hey, look at me, I'm not racist'. That's easily done when you're in the position of not facing prejudice, setbacks, an unequal playing field when it comes to opportunities, or even that the police may kill you, every single day of your life because of the colour of your skin. It's a freedom with which, very sadly, black people have not been able to live.
I wish every teenager could read Malorie Blackman's YA Noughts and Crosses trilogy. In these novels Blackman inverts the hierarchy, so that it's the Crosses (black) who are the dominant race and the Noughts (white) who are subjugated. She invents her own version of the racially inflammatory language black people are constantly forced to confront (Crosses meaning closer to God but ironically also angry), Noughts meaning nothing. She invents a sort of racial segregation that's not dissimilar to South African Apartheid. As a white reader, absorbing this unputdownable novel was a highly discomfiting experience. It gave me a glimpse - and a glimpse is all that is possible - into what living this way must be like.
The 'all lives matter' platitude is very like the NAMALT/victim blamers defence when talking to women who, like me, have been victims of male violence, rape and sexual abuse at various stages of our lives. No man can understand this, any more than I can understand black lived experience, or the experience of black women rendered marginal because of their skin colour as well as their sex.
It's structural racism has to be tackled. We have little hope of conquering individual racism - or simply associating it with skinheads and an England flag which is very oversimplistic - until it's been tackled at this kind of institutional, structural, embedded level.
I hope if this tragedy has one even slightly positive outcome, it will be that it causes people to question this - and also themselves and their own attitudes - more.
