I don't agree she should be kicked off the competition just because of a supposed rant, and she is splitting opinion due to the fact she appears to be the odds on favourite of the show, i personally do not rate her or see the outstanding clamour about her, but then that is my personal opinion and does not make me right or wrong about her.
I hope she does well and enjoys her experience on the final, however the only thing i have an issue with - and this goes for all contestants really - is the manipulation of the contestants for column inches.
Take for example Susan Boyle's appearance on the semi final, you can not tell me that the image of the light around her head as if a halo was unexepcted, her singing began terribly (probably nerves), but in her defence finished quite well. I still cannot shake the niggling feeling that if she had done an ali-g style rap she would have still have won due to the manipulation of the media, which to me undermines for me the actual real talent in the show. If she was an attactive blond or dark haired lad she would be looked upon the same as the postman and would not have got anywhere near the semi finals.... however it seems these shows quite obviosuly now are actively on the lookout for the poster girl/boy to hang the show on and this year it has been her.
I do not agree with the nastiness now creeping up against her, but then again i see the adulation she is been lavished with just as creepy.
(all my own personal opinion obviously)
