[quote=scaredycat] What the groupie wants is the power and money of the mark; the stalker wants the womb. [/quote]
And that’s the principal difference between a groupie and a stalker.
A groupie “is a person who seeks sexual and/or emotional intimacy with a celebrity or other authority figure.”
Far more often than not, the stalker isn’t interested in the celebrity/authority aspect of the mark. I’m guessing that out of all the stalkers out there – let’s assume they’re mostly men just for argument’s sake – that the vast majority focus their psychosis on “normal” folks they see in their everyday life, as opposed to celebrities.
So, I would agree that a male stalker of a female celebrity would definitely be analogous to a female groupie. But I suspect that the former is a very small number in comparison to the latter. Thus the analogy is a bit weak.
