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”.
I’ve seen other men giving me answers to questions my wife asked to many times. Of course thats not dangerous, but thats still asshole-behaviour and you can recognise a whole lot of this behaviour everyday, if you just listen to your female coworkers instead of giving them the side eye. They probably wouldn’t feel the need to “not-you” you, if they KNEW you are not a possible asshole.
