Fair point, but in most scary movies back them they were just the damsels in distress that did nothing except look pretty, as was the case with Fay.
I mean, the whole tone of the movie was "women aint nothing but trouble, men can't think straight when there's a pretty face." Jack, the supposed hero/love interest is a total misogynist, he just makes an exception for Ann because she's is sweet and pretty. So yeah, I'm pretty sure the writers of THAT movie at least didn't think much of women back then.
And technically, the men used Ann/Fay as bait to bring down Kong, she really didn't do anything. She was nothing more than the doll used in the Kong scenes.
