It was actually you who assumed that I thought it was only women who are weak-minded. I believe that both men and women can be weak-minded under different influences, but I am wondering if 50 shades of Grey might be one of them for women.
No, not misogynist at all. Another way I could also put it is that right-minded women would not expect more than sex out of a casual relationship and weak-minded men might do.
Thus implying that women who are not quite as right-minded (whatever that is in your world) than other women (or men, excluding those who are not quite right in the head and susceptible to these things), might expect more out of casual sex than a right-minded woman would.
I came to the conclusion that the question of this poll is redundant seeing as you had already come to the conclusion that people, regardless of their sex, would only be influenced by novels such as Fifty Shades of Grey if they were not quite so strong willed.
I understand how you are only enquiring about the female mind - one does not always need or want to know everything - it just seems that you have already answered your own question.
