Yet another take on Big Brother

Amid the media frenzy elicited by journos' attempts to provide ever more insightful (and inciting) commentary on racism in Big Brother -- and it is unquestionably racist -- haven't we lost sight of a fundamental problem with this sort of media?
So she's getting paid to appear on the show and should've had some idea of what she might be in for, but this is TV based on abuse. Channel 4 and Endemol do themselves and their audience great discredit by continuing to broadcast this shit. What sort of sadism is this? Are people really entertained by watching someone be abused in this way? I'm not surprised that they've been so many complaints.
Of course you can try to justify some aspects of this broadcast: racism is now (temporarily, I'm sure) top of the tabloid agenda, while the show is exposing issues we have in the country as a whole which we rarely want to face up to.
But remember that the whole point about racism is that it's not just the individual in the direct line of fire who is suffering abuse. There's collateral damage to everyone who's visibly ethnically different and who has experienced similar behaviour.
The broadcasters, by not even warning the offenders over their behaviour are condoning it, almost certainly for the sake of money. It's a slap in the face for an audience presumed to be psychotic voyeurs, and a kick in the teeth for anyone who hates racism.
