Yes, Jamie Fox's comment was racist. While Mily Cyrus may be a little bitch, there was no need to refer to her race. However, Michael Jackson was black, and he didn't and doesn't belong to anyone. He belonged to himself, as do all of us.
I'm willing to believe that Jackson wasn't a child molester. I don't know. Your description of him seems as likely as the other, but he was found not guilty, and I don't have any facts to disagree with it. So I've got to let it go, even if I felt a little creeped out by him.
But I draw the line at calling him a "miracle". He was a very troubled person who was taken advantage of by everyone around him, and he might have deserved our pity. And he certainly had an extraordinary talent. But I don't think he was any more of a miracle than the sunrise is.
