I stuck about a minute of the first clip and I couldn't take any more ... and it's not even my country!
Sadly, this kind of inverted Blaxploitation took root over here thanks in large part to the stereotypes of Hollywood and the songs (loose interpretation of the word) of Rap Artists.
Basically, we lost an entire generations worth of progress on racial integration and now the pendulum has swung the other way, such that ordinary people (rather than just members of the BNP) would quite happily see all the immigrant population "shipped back where they came from", regardless of the fact that many are completely legitimate British subjects, having been born here.
It's quite simple really, if you want to be American or British then be just that, don't try and play this hackneyed "oppressed minority" nonsense any longer, it lost its effectiveness a long time ago. If there are elements within your 'ethnicity' who bring that group into disrepute, then deal with them, don't glamorise them. Following that path only promulgates and prolongues divisions that should be long gone.
