Fifth Grade Psychopaths

I saw this article online this morning and it really bothered me:

Apparently, these 2 FIFTH GRADE boys (ages 10 & 11) were caught on a bus going to school with a knife, a gun, and a rape/murder plan. They confessed to the police (after being caught) that they were going to rape and murder another fifth grade student--a girl--because she had made fun of them and their friends and this made them angry. The police were very shocked, and as the story states "state law specifies that children between the ages of 8 and 12 do not have the mental capacity to commit crimes." I would say that before I read this article I would have believed that but it is obviously not true anymore. The police also asked the boys if they understood that rape is not about sex but that is it about a display of strength and power, and both boys said that they fully understood that! 

LIKE WHAT THE FUCK?! As the author of the article wrote "While I understand that they're too young to fully appreciate the gravity of what they had planned, that doesn't diminish the atrocity of the fact that a 10 year old was able not only understand the gendered power dynamic inherent in rape, but also to plan to use it as a punitive measure against another child." I, personally, never knew that young kids knew what rape was/what it really means, but I guess that children are more and more seeing images of it on television and in movies. The author wrote "Children and adolescents are constantly exposed to the insidious ubiquity of patriarchy and rape culture, in which violence is eroticized, male sexual aggression is affirmed, and assumed male access to women's bodies is normalized." It is just like we talked about in class, with Mackinnon's article on sex. Everything in our scoiety--especially sex--it centered around this assumed male access to women's bodies. So much so that now even little kids are starting to understand it at a younger age. It just makes me sad because I feel that as a woman (and just as a person in general) that there is hardly anything that I can do to change this mindset. How do we keep our children from becoming like this? How do we teach people that others are not there simply for sexual access?
