DIO was not a Satan worshiper. That's as bad as saying Ozzy is.He did many songs about occult-like subjects. Songs about, myth, historical related, or fantasy, and of course religion. Whether dark, or white. Just because he sang about a specific subject does not mean he practiced anything. It's ashamed people would protest at anyone's funeral. And disgusting that these same people protests KIA funerals.
