Michael Jackson and Kelly Clarkson both did shady stuff to children. Michael Jackson said that there is nothing wrong with sharing a bed with unrelated small children. Kelly Clarkson said that there is nothing wrong with physically beating a small child.
The thing is, though, only one of them made "Billie Jean" or "Beat It", and the other is just a typical karaoke country singer. So no surprise people gave Wacko Jacko a pass.
