The decision to sleep on a train is yours to make. The fact that I was asleep does not, in any way, excuse the drunk man's behavior. We need to respect people, especially in our shared spaces. We need people to keep speaking up. Not only for ourselves but for those around us as well -- we are not alone!
Being a passive bystander is not a "crime." If we have any hope at all of putting an end to incidents like these, we need to stop doubting the accusers and start holding rapists, abusers and bullies accountable. What we don't need to do is point fingers at those who weren't to blame for their actions.
We all victim blame. Even after years of education and training in this area, I still do it all the time, and have to consistently be aware of my thoughts when I hear of a sex crime. Which is exactly why we need to be aware of this and try to recognize when we go there and choose to think differently.
We must recognize the value that comes from pushing the boundaries of what is acceptable, of breaking taboos, of standing up to thugs. Not to do so speaks to a form of cowardice only supplanted by the news outlets who have refused to show the cartoons and the even more pathetic attempts to justify that decision. It gives those who wish to intimidate us exactly what they want: self-censorship brought on by fear.
The surest way to avoid ever having your most private photos shared publicly is to not take them in the first place. This is the philosophy behind the most common advice given to teens, among whom the rates of "sexting" continue to rise. Trust no one. Share nothing. Even better: Take nothing. It's ridiculous logic.
