Just to repost my comments to another forum member on another thread, your reasoning is completely flawed.
The whole point of BB is that we are presented with a disparate group of individuals who are left to sink or swim by virtue of their own personalities in an environment where even the most trivial emotional responses are heightened and amplified. The audience visits this human zoo and we are drawn into intimate proximity with these people but still allowed to retain our privileged position as spectators.
BB basically is pretty reprehensible television when you really think about it. It appeals to our base, judgmental instincts and gives us an illusionary sense of power by being able to decide which contestants stayed in the house and which were evicted. To achieve this, BB actually *legitimises* dislike of certain housemates, hence the present negative voting system.
To imply that forum members are being self-righteous when they criticise Cameron, Ray, Steph etc. is completely missing the point of what BB is all about. Any flaws we forum members display in their daily lives are irrelevant. The fact is that we didn't choose to put ourselves in the public eye. But the BB contestants *did*.
