Well, I haven't, and nor has my daughter. In all my years, neither my sister nor I have faced antisemitism. It doesn't exist.
My daughter was a camp counsellor at a cJewish amp in Beverley Hills. She couldn't believe how entitled and spoilt the kids were.
My late father was a holocaust survivor. That is what antisemitism looks like. And both my daughter and I are aghast how 'treat the stranger in your land well, for once you were a stranger' is ignored.
I once attended a Purim dinner and mentioned a point of ethics in sales. This guy who owned a business (long story short) said that it was more important to feed his family than to be ethical. .
