A few of the people you’ve listed I don’t know much about. But I don’t think anyone’s talking about banning celebrities. Celebrities are people we tend to admire and “celebrate.” However, I don’t consider Adolf Hitler and Sadaam Hussein to be celebrities because I don’t know any “normal” people who celebrate or admire these monsters. And devils like the two aforementioned belong in a select group of evil that infamously distinguishes them from other criminals. And as a Michael Jackson fan, I’ve never considered him any kind of criminal because I think he was indeed innocent.
