Just because a person is a fan of someone, it doesn't mean they want to fuck him. Maybe it is for you, but I doubt "Hey, I really love your work, and you're SOOO cute" equals consent. Rape, AFAIK, is about power and control, not sex. Sex is the means to demonstrate perceived/desired power, but it's not the reason.

Of course, I think obsession with this case is a little creepy too.
