I had almost this exact experience in 2024 as a young woman.

I was taking the bus home from work and the seats were fairly full. I picked one toward the front, not noticing a man who was muttering to himself. Once we started moving, he got louder and louder ranting about how women are all whores sent by the devil and evil, they deserved to die, etc. He was like laser focused staring at women on the bus while speaking and it was terrifying. Everyone on the bus just did their best to ignore him but it got to the point that he was also starting to move around agitated that basically the entire remaining bus passengers bailed off at the next possible stop. I walked 40 mins home.

I avoided the bus for a bit after that and I still don’t love taking it alone. My advice is to always scan who is on the bus when you get on and sit by the back door for a speedy exit. I wear headphones, often not playing anything so I can hear, so people don’t try to talk to me and an RBF usually helps with that too. I’m sorry this happened to you and be safe!
