Um, the Constitution gives Diem the right to be an idiot and not get arrested. It doesn't get her out of being called an idiot.
Diem wanted special treatment. That's not what the competition is about. It doesn't matter who deserves it most. And you guys are being uber-sensitive about her getting criticized. No one said she's a baby-killing bum-kicker - they just said she acted ridiculously and was out of line for her rant. The same was said about Lynette when she acted like a 7 year old. Much worse has been said about Derrick.
Just because you are a fan of this reality tv character does not mean that you need to martyr her and stick her on the cross. No one is tearing your girl down - just criticizing her actions here.
If Diem (or as you call her Cancer Patient) wants to pay her hospital bills, the answer is a JOB - not an MTV challenge. Yeah, it sucks - but that's reality - not winning $125K in "exile."
