The most I read about this shit, the most I think that whatever the director wanted to say, was not only lost in execution, but her grievances were in a direct contradiction of our own and that's why the message is lost.
I get that her, being from a muslim environment, wants to make a point about how women should be free to explore their sexuality and you shouldn¡t put a five years old in a burka.
The problem is that she doesn't realise that, even though we westerners DO NOT put our girls in a burka, we don't let them dance around like whores either. Or, we shouldn't. There are definitely parents, specially mothers, who pimp their girls up because it's trendy and fashionable. I know, I've seen it and most people are against it.
Thing is, we are condemning the movie for what we're seeing and yes, that's wrong. Alas, there are also many women who encourage or don't pay attention that their very young girls are fans of Selena Gomez and Cardi B and they copy what they do and are. Remember that scene from Mean girls when Regina's sister was copying what she saw on tv? Same situation. I get that she wanted to make a point out of this while also saying that her strict religious family shouldn't be trying to exorcise children for dancing.
I guess her main failure is present actual children doing this when there were better ways to show her points. I really don't think she intended to "sexualize" girls to pander some old pedophiles from the industry, she just did so because she was clumsy and very disconnected with what offends the majority of the audience.
