If they're leering at her (she said she can "feel" their looks, which could mean looks of moral judgement or of objectification/lust), I can start to understand why she'd be afraid. But there is a subjective element to interpreting others' body language, and bringing religion into the complaint makes me think prejudice might be coloring that.
However, when it comes to setting public policy that trades off against individual liberty, authoritatively stating which of N cities is safest, and so on, I think the bar should be higher. Statements should be based on hard data such as numbers of violent attacks. This isn't practical for individuals (imagine: "based on extensive personal trials, I was murdered ten times as often by people who...") but is on the scale of cities/states/countries.
