For a username? I love other artists too.. not as much as MJ but I really love them!!! There is no problem really...
You love Michael.. then just stay.
All because of our username? Childish, childish of 'em. Well, you can tell them to stop hating on you. If that doesn't work, than just don't go on the MJ club where people bug you. You don't have to leave. You are great. ;)
