I agree with GreyGardens, I have never witnessed any aggressive racist shit like that in my Brixtonish area of S London, but people like her, and the originators of the vile YouTube comments exist and we should never be complacent, or imagine that racism is solely the territory of an unhinged, uneducated anti-social demographic like her.
My child was called 'chocolate face' by a smart expensively dressed articulate boy on a cupcakish sort of Sussex campsite, and his friend was told to 'go back to whatever black sort of country you come from' by a child from a prep school in Dorset while they were all on a school trip to the same centre. Do they get it from their parents, too?
Poor, poor child - he does look anxious, to me. And poor other children - I'm bloody glad I wasn't on the bus with DS listening to that!
