I just don't think the second part of your post there is actually going to happen at all. If it were, if there were really going to be some kind of "culture change", then I'd say great, take 'em all down. As it stands, it looks like its just a hot and sexy news story and a few dudes will go down, but for the most part, the vast majority of abused men and women will see nothing change at all. Eventually, the "feeling" will be similar to the Obama effect. This kind of abuse will be "over", and it'll just get nastier as it ferments beneath the surface of the mediascape.
I genuinely don't see how we can deal with this properly. It's not enough to say that people "shouldn't act" on their urges/desires/what-have-you. It ignores how widespread it truly is, paints it as some kind of bad apples situation when its far bigger than that, and has deep, deep roots in the history of humanity. It's not going to go away through the current craze, and in fact, I think it might even get much, much worse. I also don't subscribe to the notion that this is about power and has nothing to do with sexuality. That seems insane to me. Sex and power cannot be separated like that, it's not how humans work. There are people whose actual power in their own lives is all but nonexistent who commit sex crimes, who abuse people close to them, who abuse strangers...it's not for anyone to sum up, because it's one of the most complex issues that humans have dealt with across history. Off with their heads was never a good way to deal with widespread societal horrors.
I just mean that there is no solution in this, only further hurt. I'm not saying that people shouldn't come forward, or that people shouldn't be punished. I am not apologising for any of the bastards, but I also don't think there is any empowerment here, there is no catharsis. This is only another manifestation of something far darker in the human psyche that we need to grapple with much more seriously than whatever this "moment" provides.
