I didn't think you were defending child rape, but I do disagree that what Lucas and Spielburg are saying is anything like the kind of kink often found in fanfic. (Except for creeptastic fanfic that tries to justify pedophilia and rape.)

If it were that the woman were twenty and the man were sixty, I'd go, "meh, whatever." If Indy was supposed to be a dark, selfish, creepy type who made big huge horrible mistakes and was trying to redeem himself, and Lucas and Spielburg were addressing this as such, I'd be okay with it. But Indy's basically a Big Damn Hero who's sometimes snarky. Making that kind of character a rapist means you're saying rape is not a big deal, because even a Big Damn Hero can be seduced by some slut, and hey, it's not HIS fault, obviously every female has magic powers over the penis which they wield with knowledge aforethought and men are helpless to resist.

I probably sound more argumentative than I mean to be. Just, no, I don't think it's at all hypocritical to condemn what these dudes said and still enjoy certain kinds of fiction that the authors realize, and present as, that kind of fiction.

A big age difference between characters can be a really fascinating thing to explore. I'm writing some fanfic now in which one of the characters is over 2000 years younger than her lover, and it's not even kink -- they're just a really really really long-lived race. (The woman is over one hundred years old.)
