I'd like to fancy our society ideal, but even with the LGBT/women rights movements going around, we are still at danger from men. No, they're not born with an urge to beat or you know, but with a little alcohol consumption, someone you know can turn into a completely different person. The fact is we just don't know, and that's where personal responsibility comes into play.
You, and everyone else should invest time into self-defense courses. Why let yourself be caught off guard when something does happen? Being paranoid about it simply won't do, you need to take it into your hands to be sure you can take care of yourself should the situation arise, other than doing that, it's all up to fate.
