I want to add that I was thinking of two celebrities when I posted this (both are deceased).
Karen Carpenter and Marilyn Monroe.
There are many in-love fans on Karen's numerous fan pages. All the comments they post are superlatives, in other words, the highest praise they can give.
Marilyn Monroe: Fans constantly talk about how beautiful she was and that she is effectively speaking the most beautiful woman ever.
What seems odd to me is that both women no longer exist but to their fans, they appear to be very much alive.
It's one thing to pursue an alive woman who may not share mutual feelings toward you. But what about a deceased woman who cannot possibly interact with you in any way or fall in love with you?
What does this type of fan worship mean? It's as if you choose to love and adore someone who is absolutely unobtainable. Yet, many living women are also unobtainable for various reasons. It's like a commoner wanting to consort with the Queen but believe me, she has her King and no one can hope to usurp his position.
Maybe part of the appeal of celebrity worship to a Stan is that he can never hope to realistically "possess" the object of his affection/madness. Maybe that's what draws him - the impossibility of his crazy dream. Maybe he's not really interested in an ordinary person he already knows. He needs something he can obsess about. Can you obsess about an average person? Well, I guess people do that, too. But the celebrity represents someone beyond one's means, social status, income level, level of intelligence, etc. So, maybe it's wanting someone who has things we want as opposed to wanting the person herself.
Just more random thinking out loud. That's all.
