'She couldn't say no" - of course she could, she's an adult, adults say no all the time. And yes, sit inside the car, call a friend, refuse to go in, dump Max on the spot an call a cab. All of those are valid actions - they aren't easy, but they're indicative of somene with firm boundaries that they're going to keep.

Your ecstacy analogy is misleading and not comparable. If someone spikes my drink without my knowledge or consent and I drink it - that is without my knowledge or consent. That is 100% wrong. In the same way if Max had just airlifted them to a party without telling her it was a sex party, then my argument would be null and void.

If someone puts ecstacy in my drink, I see them do it, then they lift the cup to my lips and I CHOOSE to drink it, then I have consented. I may have been pressured, and I may have been encouraged, and I may enjoy the company of the person who has put the ecstacy there.... but I'm still an adult and I still made the choice to drink. I have culpability.

At the point they hold the cup to my lips, I can refuse to drink, knock the cup on the floor. Hell, I can even partly drink some and spit it out (that's the ecstacy equivalent of this story) but I'm the person who makes the choice. Retrospectively blaming your poor decision making on circumstances alleviates taking responsibility for your actions and is an act of self infantalisation.

My argument isn't that Max is an upstanding great guy who deserves a round of applause. My argument is that he is not the person solely responsible and shouldn't be blamed as such.
