Queenie, sounds like the guy is less of antisemite and more of a nut case. These are the type of people who often commit crimes of violence. I have no doubt that if there were no people around, this guy would have been very capable of assaulting Yossi. There are far too many untreated mentally ill people walking the streets – undiagnosed a/o unmedicated or undermedicated. Often, one day these types just “snap”. If they have access to weapons, real tragedies can occur.
Yossi, you are lucky that you just had a brief encounter with this guy and that you are safe and sound.
