before the day is done

(WARNING: This post contains discussion of sexual violence.)
I'm going to be honest. I've been struggling so far this year. Some of it is internal: stress and new job and too many deadlines and a lot of emotional commitments and just AGH. Some of it is external: new job (yes, that counts both ways!) and old job and freelancing and what's been in the news lately. Today really got me; I was catching up on Kat Howard's blog, and hit on this post, which led me to Amanda Palmer's blog, and then on to news articles about Steubenville. And then I got really, really angry.
How can people treat other people like that, like they have a right to do whatever they want? And the bystanders . . . people were taking photos. Videos. People were uploading photos to the Internet as the abuse was happening, but nobody HELPED her. What is wrong with America that we raise our children to stand back and document the wrongdoing but not do anything to stop it? And that reminded me of that poor man who was pushed onto the subway tracks in front of the train in December. People took pictures. Nobody tried to help him.
I could go on and on about this sort of thing, about how I often feel like women are in an abusive relationship with America due to the prevalent rape culture in our country, about how so many of us have been abused but that doesn't make it right or okay or acceptable. But I think that my earlier anger short-circuited my brain a bit. All I am now is sad. Sad that a teenage girl can't be safe at a party with her friends. Sad that so many of us have to endure bullshit like that. And I don't want to be sad. I want to do something about it. But what? Does anyone out there have any ideas? How do we combat this sort of behavior? What do we do?
