OH, I get what you're trying to say, I just don't buy it. In fact it sounds like something a 15 year old would come up with. Probably at night in his bed.
I've a feeling that scene was in the script long before it was filmed. and the actress in question has been nuder. So we're not talking about something sprung at the last minute on some innocent jut off the bus. And I've no illusions as to why it's in the film. It's a fun little scene. But its not the big deal you seem to think it is. Especially given Star Trek's history with the female form. It's history of skin, sex and sensuality is well documented. By comparison the scenes in ST09 and STID are pretty tame.
Again I'm not a feminist, nor am I some idealist.
She could get tag teamed by a gang of klingons for all I care.
The point is that it's completely out of context within the film.
It has no interaction within the film, it's their because the audience doesn't need to take the character seriously.
To me that is horrid judgement in film making.
