i made some suggestions, but it isn't my industry. getting it into the hands of a prominent rapper would go miles, and i believe my suggestion of someone like snoop dogg would be very very effective.
I think class and religion unite people more than skin colour (at least in Britain).
On a typical Manchester housing estate the black people of Caribbean and a Christian heritage have a closer connection with white British people than with Islamic black Somalis living on the same estate.
ie culture is not defined by skin colour - most families on these estates are mixed race, but share the same religious heritage (even if they no longer subscribe to those religious beliefs).
In fact the average Manchester housing estate tends to be very mixed race - but there is a clear disconnect based on religious heritage.
Most white kids on Mancheser housing estates would identify themselves with black (Afro-American-Carribean) culture, rather than 'traditional' white British culture.
(apologies for going on about Manchester, but that's where I grew up and so I know what it's like)
