She didn't do anything extraordinary, though. A crowded bar is hardly an "unsafe place," for crying out loud. And I would ask you what you, specifically, think she should have done differently, but who are any of us to judge in the first place? Going to a bar with some friends for some beers is eminently normal.
I am not accusing you, personally, of justifying sexual assault. But people can and do presume that a woman who is assaulted was in some way foolish or asking for it. And they make legal decisions on this basis.
As I said, I get that you're making a narrower point that speaks to reality over principle. But it is spectacularly unhelpful and in extremely poor taste to counsel a victim of sexual assault that she is responsible for her own safety and, by implication, she needs to be or should have been more careful. Why do people feel like it's OK to lecture women in this way?
Finally, I must point out that your experience of living in unsafe places is a very, very small subset of a woman's experience living in places that might otherwise appear "safe." For all practical purposes, men don't have to worry about being sexually assaulted. This is a case in point: she was at a bar, among numerous fellow professionals, many of whom she considered trustworthy.
