I actually knew a guy who dated a 14 yo girl at the age of 25 or something. He told me about that casually and when I confronted him about it, he said that she lied to him that she was 15. 15 is the age of consent here. Well, it doesn't make it OK to date a 15 yo in your mid-twenties. But even if it did, he didn't seem fazed that she lied and she was under 15! Either way, he started defending himself saying it's not bad or anything because people used to romance girls as young as that once upon a time. (And similar asinine arguments that I harshly rebuked.) I gave him a talking-to so harsh he consecutively stopped dating her.
According to him, they only met twice and nothing more than hugging happened. And I believe him. He wasn't much of a predator. More like a VERY desperate virgin guy. The girl apparently was the first girl who showed any interest in him and he conveniently ignored her age and was swooped in romantic upheaval.
All that being said, it kinda sounds cool if I imagine that I actually saved a child from a terrible abuser! Hehe. Well, I do believe I saved them both from nasty consequences...
So, you see, if Polański was similarly swooped and hugging was all that happened, I'd be willing to give the man the benefit of the doubt, just like I did to the guy I knew. But Polański had oral, vaginal, and anal sex with her. This makes defending what he did undefendable in itself. And makes you question why Tarantino would do that.
