This thread should just be locked. It's not even a RIP thread anymore. It's just a Michael Jackson free-for-all thread now.
As whacko as he was, he still deserves respect. If you don't like him, so be it, but don't go around cracking jokes about the things he did. If you really can't help yourself, then open your own thread bashing the bad things he did. Ruining a RIP thread won't do anything.
