Has Miley Cyrus Become Too Sexualized?

Parenting expert and three time father of the year (whatever that means) Joe Kelly spoke to TMZ about the sexualized marketing of Miley Cyrus.
"Miley Cyrus is the latest in a distressingly long line of girl celebrities launched on a trajectory where they are marketed as hypersexualized objects." He doesn't blame Miley, but thinks corporate marketers should be held accountable for "marketing precocious sexuality to young boys and girls."
We all know sex sells, but should it be used to sell the image of an underage girl?
