If the possibility that a man will treat a woman badly (everything between belittling and straight up murder) is high enough, it is a life insurance to expect every man to be dangerous until proven otherwise. Its the same logic as “don’t talk to cops”.
No, it’s not life insurance. It’s pathological paranoia that doesn’t effectively improve one’s safety. If you go through life with an incredibly simplistic model of judgement, where any interaction with men or cops is dangerous until proven otherwise, you are simply trading one set of risks for another. There are many situations where a certain cop or man could be in a position to help or protect you, and you might fail to recognize that.
If you’re not making any distinction between “belittling and straight up murder”, then you’re really just handicapping your ability to distinguish people who are actually violently dangerous from people who are just normal people. Most people act like assholes on a regular basis, but that doesn’t make them dangerous.
