The eternal answer to your question which goes to the heart of her story is: when a girl chooses to attend a drunken party with 4 boys at one of the boys’ houses when parents aren't home, wearing nothing but a bathing suit with top over it, she has lost all claim to innocence. Any 15 year old girl who attends a drinking party with boys older than her knows the score. Girls know. She had no business going to that party and later blaming them for traumatizing her. No one should sympathize with her poor judgement and its consequence, which according to her was actually par for the course when it comes to nerdy, horny, drunk boys and promiscuous, overly-sexualized teen girls. This has been going on at least since the Roaring 20’s as far as I've seen documentation for (common in silent movies). This story grew legs solely due to the fact that we are in a strange moment of history when right is wrong and wrong is right.
Your comments are all apt, except that teen aged sexual exploration has been going on since the dawn of the species--not just from the '20s. This whole excursion in disrupting the judicial nomination process is a total travesty
No one excuses what the girl says happened. If it did, it was inappropriate, certainly. After 36 years, even if there was some corroborative testimony--which there does not appear to be--it would, for all the reasons you cite, be irrelevant.
Here is something else to consider--as it goes to the motive for the accusation at this very, very, late date:
