If you want a weak spot. It is their confidence. Female early childhood plays revolve around being adults. Most of women build their confidence on their sexuality, since they have no independent mind. They stuff lot of things in their vagina and then return to play their image (whatever suits for them). As "experienced" world citizen, they get some kind of immunity towards criticism. We also see lot of times male's trying to pet their egos against these "strong" women. You now know what it is based on. Destroy it.
All the best for my fellow fighters. The loners, ugly, shy, nerds, geeks. I feel for all of you.
