They are also attacked by people they don't know. I've been groped in public by strangers, as well as followed, and otherwise made to feel unsafe. That means that I (and every woman I know most of whom has also experienced similar things) has to be vigilant, aware, and afraid on a regular basis in a way that most men don't have any experience of. When was the last time a male trail runner was found dead or had experienced fear while out for a jog? Haven't heard of a case of that, and yet every woman I know who runs by herself has multiple stories of being bothered, followed, and taking precautions to not end up a statistic. This is my point.
You do not have a higher chance of being assaulted than your wife unless you are in prison, in a gang, running from the police, live in a poor urban environment, or like to get into bar fights. She might well be assaulted at work, in a restaurant or bar, in an elevator - all places that you are allmost certainly never going to be attacked.
There are some men who have to live that way also, but for the most part, this sort of danger and vigilance to protect themselves from it affects nearly all women in a way that most guys are so clueless about that they want to argue about it on the internet.
