Rachels past is not being thrown in her face all the time by most. If anything, her supporters are bringing her past up continually to try to distract from the real problems people have with her.
Forget the past for a moment, and consider the current situation.
Rachel has custody of 2 kids and there are 3 more who exist because of her. She was old enough to know her choices when she had the last 2, and to be responsible. She wasnt. Not judging, but...NOW, she is CHOOSING to live off assistance/all of us weather we like it or not. She is choosing to get free rent/expenses/child care, etc...if sher can go to auditions, she can get a JOB or 3. If that makes chasing fame harder or means she has less time/money than she does as a leech on society, tough. She may have been incapeable of working /being responsible before, and if so, not judging. But now? Get a job, support the kids you made, and then what you do wont be a problem to those who resent ya right now.
AS far as her whinging that if she doesnt get far opr 'win' her chance is 'over', that screams entitlement/gimme! She has had media exposure and, if she got booted today, could easily get an agent and make a living. Butr to do that would require work, and it wouldnt be handed to her. But, the chance is there. She probably knows it, too, but wants it handed to her lik ea rent payment or spending money or a free makeover.
As far as her voice, it is good, not the best this season, but good enough to not be ridiculous in the top 12. BUT-what she does with that voice(forgetting words, sloppy poorly thought out rendition of Chasing Cars) is an insult to the people giving her the chance, and to all the equally good singers who work hard to not mess up and who arent a drain on society by their own selfish choosing.
So quit bringing up her past, because those of us who resent her are far more concerned about the message the show is sending by using her for ratings than about the past and so-called-being-judgemental being thrown up to distract from the real issues people have.
