I can't see why anyone would hold anything against any of the little girl dancers. They aren't nearly as annoying to me as some of the kids on Toddlers and Tiaras. I haven't seen every episode, but they don't seem to talk back, and they don't seem to be mean to each other.
In fact, I really feel sorry for Chloe. She seems very on edge. I think between her mother and her dance teacher, she's not really getting any joy out of dancing. I think the fact that she bursts into tears so easily is just her way of dealing with the tension. Plus, every time I see her, I imagine my mother seeing her and insisting on cooking her a meal. I know she's probably thin because of metabolism or her dancing or both, but my mom worried about everyone having enough to eat--the family reunions on her side of the family were epic in terms of the amount of food everyone brought; at one reunion, some kids from another reunion who happened to be sharing the shelter house with us and who had been playing with my younger cousins all day long just went through our line at supper and we didn't even notice until their parents got all embarrassed about it, particularly since the kids announced, aloud, that they'd done it because we had better food.
