Bono told Chuck D once that he understood the struggle of the black American male, because the Irish are the "blacks of Europe"
The Irish are the blacks of europe and the Dubs are the blacks of Ireland.
He stole it from the commitments:
Do you not get it, lads? The Irish are the blacks of Europe. And Dubliners are the blacks of Ireland. And the Northside Dubliners are the blacks of Dublin. So say it once, say it loud: I'm black and I'm proud.
I take everything in that film as gospel, so i'm with Bono on this one.
