I'd like to know from the OP exactly how this man knew that they were Jews. I see one OP wants to kill the person, one or more wants him removed as a security risk for expressing his dislike for Jews. I'm gay and when I was younger I was sometimes very concerned for my safety. If I really thought something was going to happen I would call the police. If someone insulted me and said they don't like f***, I would get away from them as soon as I could. I would not automatically call the authorities.
