DB - I'm not sure you read the OP....
Another husband first here. In my case I'm sure it's because of a number of aspects of my personality, some of which are likely due to my gender. I'm not very social, and I'm more confident in my ability to think for myself than my wife, both of which make leaving easier. I'm also an INTJ (personality that is least likely to believe in god(s) and also has a higher incidence in males.).
Women tend to think a little more emotionally, and since cults rely heavily on emotional manipulation, this may be a disadvantage. On the other hand, that may just change how they wake up, since there's certainly plenty of emotional abuse in the cult. In some places women are also more likely to be under socialized since they may be less likely to work or they stay home and take care of the kids, etc whereas men may have more of a social structure at work. This could certainly lead to a higher dependence on the cult and therefore make it less likely that they'd be willing to leave.
All of these factors are by no means universal and probably only make incremental impact on the likelyhood of leaving though, and I don't think the difference between men and women leaving is necessarily huge. An informal poll here may also be somewhat skewed, since it seems like men are more likely to take to internet forums than women (at least I'm assuming that's the case based solely on the leg humping that always occurs on forums when it is discovered that a poster is a woman)
