Well, to identify with someone, you should share something with the person. Celebrities often "offer" plethora of various attributes to identify with, but I don't think they are honest. If someone is a celebrity, it implicates the person got a certain status and he/she needs to wear a certain "mask" in order to allow yourself to be popular and resonate among the broadest masses (politicians, actors, singers, etc.). This is one of the reasons why some formerly interesting people lose their appeal once they become celebrities (certain writers or doctors for example). Unless you know the person personally, you can establish the sympathy only on the basis of superficial information which are unlikely to be genuine because of the character of their status. Celebrities often gain extreme popularity in exchange for losing the appeal to the people whom they know personally.
