I don't think you understand what I was saying. In no way do I think it's ok to blame a victim. I happen to also think that the world is dangerous and that we need to take common sense steps to protect ourselves. Rape is a unique crime, do it's hard to make an analogy with other types of crime, but I simply think that exploring ways to keep oneself out of danger is worthwhile.
Of course the world is dangerous. It is absolutely more dangerous because of attitudes of complacency towards bad behavior, especially rape. Whether it was your intention or not, your statements imply that a culturally acceptable danger is the ever-present threat of rape by men. Moreover, the onus of responsibility for a woman's safety is her own preventative measures. This type of rape culture, in which the threat of rape is accepted as pervasive and ubiquitous, is NOT OKAY. Plenty of women who have taken appropriate steps to protect themselves have been raped. More importantly, young people, male and female, should be entitled to do lots of things, including frequenting bars, without feeling emperilled of the pervasive threat of male rape. I'm sure you agree with this.
