From an article titled, Feminization of America Is Bad for the World:

“Mattel’s research showed some differences in what girls and boys wanted in their action figures, Ms. Missad said. ‘For boys it’s very much about telling a story of the good guy killing the villain. . . .’ [Girls] would tell us: ‘Why does the good girl have to kill the villain? Can’t they be friends in the end?’”

And in related real life news:

Why are women so poorly represented on the front lines? Because most women can’t do the job, don’t want to do the job, and in cases where they can do it, can’t do it as well as men… A recent study has demonstrated a big disparity in women’s and men’s battlefield ability. The US Marine Corps examined over a year the impact of female integration on combat readiness and found conclusively that women cannot match male performance. Male units were faster, more effective and able to evacuate casualties in less time. Overall, the study concluded, all-male squads performed better than mixed groups in 69% of the tasks evaluated. Women performed notably less well in their use of every individual weapons system, and in addition women had higher injury rates than men. So in terms of women’s own well-being as well as the overall effectiveness of the fighting force, its ability to kill enemies and save wounded comrades, the study showed that the presence of women in combat units has a negative impact.
