Calling all MJ fans.....

I have a few questions for all MJ fans...

Don't get me wrong..its not like i dont like MJ..but not one of those die hard fans of MJ...but i wanna get ur opinions on what makes him so popular??

1.) Why is MJ so popular?
2.) Is known best for his singing or dancing?
3.) Do u think he would have been less popular if he hadnt had the surgery tat made him white?

Juz curious..tats all! :)
