Antisemitism in the NY subway

For context: I'm an Orthodox Jew who openly wears a kippa.

Some mentally ill guy came on the subway car I was in and started calling me a k*ke and saying how much he hates Jews. I moved to another car and then the train stopped to open its doors at a station for an extended time , he was walking the station looking for me and saw me, started yelling and making stabbing motions. Train closed its doors before he could get in though.

I'm fine, just irritated because if things had escalated, I wouldn't have much of a way to defend myself other than a fistfight that I would lose due to an injured hand. It feels like New York doesn't really care about our safety at all.
