What do you think of Etta James dissing Beyonce?

Etta is NO old hag. She has a right to be angry with that wolf in sheeps clothing like Beyonce. I think I would be angry too. She should have let Etta sing her own song. As for Obama asking her to do it...He didn't she was just chosen to promote Cadilac Records and no respect was given to Etta. I hate Beyonce copy cat knowles
