There are actually LOTS of very supportive posts regarding Jessica Simpson and Kim Kardashian and others. Very often, anyone with anything negative to say in those threads is ripped to pieces by other posters. So there definitely are positive people and threads here.
However, it is the nature of celebrity that people point out the misses instead of the hits. I am not sure it is so much negativity as it is pointing out that celebrities are human, too, and do not have the God-like status the media often grants them.
They absolutely ARE human, and shouldn't be given a God-like status, that's why I think it's not necessary to point out every flaw, it should be expected that they are not perfect and can very well be just like any one of us. Assuming they are perfect and then seeing things wrong and pointing them out IS like holding them up to a God-like status IMHO, (being surprised that they aren't perfect, expecting them to be perfect). We will all have different views on this though which is completely fine though right ? : ) I know a person or two that have been in that type of spotlight and to think they should simply expect it because that is the nature of being a celebrity just doesn't quite cut it for me. These are human beings we are talking about, not mannequins!
And I do agree, there are a lot of supportive posts as well, I'm not saying everything is negative.....
