The thread kept making me think about a friend of mine, who's been having very lively discussions with her class about Of Mice And Men. I'm saying 'lively' - none of her students accused her of criminalising them, but they certainly did have some of their gendered assumptions challenged!
Curley's wife has no name. Steinbeck said this is because she was a plot device, not a 'real' character. She is, however, pivotal, and we learn quite a bit about her character; I accuse him of fudging that bit 
The class assumed she was bitter, narcissistic and resentful toward men because she'd been robbed of unrealistic dreams of a movie career. A quick look at the crib notes confirm that this is the 'correct' opinion.
Yet we're looking at a woman who, at a very young age, was conned by some bloke who promised her a glamorous escape from her downtrodden surroundings. He seduced or raped her and plunged her into prostitution. I'm not surprised she was disappointed and cross. Looking at contemporary stories of, say, Thai girls who are lured into slavery by similar promises, we wouldn't feel good about labelling them stupid, deluded & twisted.
Her accidental murder was also seen as her own fault. She foolishly thought her beauty could comfort Lennie - who was already guilty of accidental sexual assault - and shouldn't have tempted him that way. Basically, she was 'asking for it'
Having tempted the clumsy oaf, she shouldn't have been surprised when he mauled her.
Drawing parallels with rape proved a little too much for the class to take in at first, so a long discussion was needed on why Curley's Wife was so dumb as to think she could help Lennie (her physical beauty is the only thing she's ever been valued for, thus all she had to offer) and whether Lennie was truly at fault.
I say, yes, he was at fault. The novel makes the woman responsible for the man's behaviour. He'd already been guilty of a similar crime; surely it's his responsibility to know this about himself, and tone it down?
Sorry, Jeanne, long post. The discussion above strikes me as a typical example, where both the source material and the study notes imply sexist values that are harmful for women. In offering an alternative analysis, I'd think it's fairly normal to be 'emotional' about it, if emotional means passionately keen to alter the students' received perceptions.
