The idea is very simple. In human society men are still dominating women and mainstream culture is still supporting male dominance and male traits: aggression and competition. Women are less aggressive and competitive than men. Movies for men are about violence and for women about family. Animations for boys are about violence and for girls about love for plants and animals. You will find that animations for small girls are most compatible with your ideas. I love animations for small girls. Check out "Tinker bell" and "Strawberry shortcake". They have violence, but in much smaller amounts than boys' animations. Animations for babies are sometimes of humanistic quality. Best is "Kipper".
My point is that the channel for compassion is blocked in humans by violence in the news and movies. Most open are small children and among them, girls and less masculine boys are most open.
