OK, not exactly "fishing."
Teach anyone any skill set, and she can use it for her own benefit. However, she is also likely to use her skills to benefit her family and community.
Teach a woman self-defense skills, and she can not only defend herself (and those she cares about) she will probably teach others around her those skills. Before you know it, she will be demanding self-determination. She will demand to be an active participant in her life and in society.
So not only will she be safer, her community will be safer.
