the fear men instill in women by virtue of existing in their vicinity is something men, especially white men, need to be aware of.
You could think you’re the nicest guy in the world but a woman sees you as a threat. Because you are! You are one. You starting a conversation on the train with a woman isn’t “being friendly”. It is trapping her in an interaction she cannot leave of her own consent out of fear of retaliation. You asking where she’s headed isn’t “small talk”. It is invasive and makes her fear for her safety by being followed. Your presence forces women to consider safety before comfort or agency. Be conscious of that when you interact with women in public space.
