Casual racists are all around us and will never go away. They need to be challenged yes. Organised racists are a different matter. They need a brutal beating, be sent home limping as an example to the rest.
Sometimes racism is insidious, and therefore hard to challenge.
A young black friend of mine who works in the gaming industry tells that, as the only black person in the office, most of the white people don't seem to know how to engage with him. When walking along a corridor he sees them deciding whether to greet him, to meet his eye, asking themselves "Well how would I greet a white person?" and trying to replicate it. He tells of how they make cheerful attempts to include him in conversation, after ceasing the conversation that was ongoing when he arrived.
Because of an HR problem, I pressed him on certain points. He was reluctant to suspect his colleagues of racism, but in the end the HR issue turned out to be a racist one.
How does one tackle this kind of invisible silent racism?
I have white South London acquaintances (Croydon & Crystal Palace) who have become more overtly racist in the last several months (since the riots, in fact...). They have hidden this from me over the years, presumably because they knew the reaction they'd get if they were more open.
I've had conversations with these people about their attitudes, and no longer see them. I recognise that nothing I have said will materially change their attitudes.
How can one challenge racism if it is hidden?
Mrs Magpie: I rarely encounter racism here in Brixton, but I know it happens. A poster on here recently experienced a racist comment in her child's school, in Lambeth. A mixed race friend of mine was recently turned down for a building job after being asked on the phone "Where were you born? (Zambia) We only employ British people". When he told me about it (again, only when I pressed him) I asked how often he encounters racism and he said "Weekly, at least." He lives in Tottenham.
When I asked these friends why they were so reluctant to speak about their experiences they told me that they can't change it, and don't want to waste time thinking about it, it's just part of their experience.
It prompted me to ask around, and the answers I have received suggest to me that racism is common, normal, and tolerated.
The racism displayed by the Lawrence killers is overt and dangerous, but the hidden racism is no less dangerous, and just as invidious.
