>Rather more disturbing — particularly here in Neukölln, a neighbourhood copiously populated by leftie Americans and families from the Middle East — is the Arabic-German barber shop called WHITE BOSS.

Yes, but it isn't a different colour, and that's what the author finds disturbing. Not sure what's to be not sure about.
