zahavasdad,
As I was walking home from Shul on Shabbos about a month ago, Someone decided to park their car in the middle of the cross walk blocking the ability to walk normally.
Just curious, did you say something to the woman about how her car was blocking the walkway before she yelled the anti-Semitic slur? Or was it completely random?
As I had to really walk around this car , this woman in the car started yelling at me how hitler did not complete the job. So I yelled back. I will not stand for someone telling that to me
I think that behavior would constitute harassment. If I were in that situation and thinking clearly (but most likely I would not be), I’d either say nothing or simply, “that was a very unkind thing to say”. And then try to memorize the license plate number and call the police after Shabbos. Especially if there were witnesses (e.g., someone walking with you or nearby who you know).
