Just spoke to several dozen American Jewish teens spending a gap year in Israel. I asked how many had personally experienced antisemitism. Virtually all of them raised their hands. I asked how many had felt they had to conceal their Jewishness in public. Again, a large majority.
One teen said she was pelted with pennies by classmates who then took out a ruler to try and measure her nose. Another said other students had put up posts of themselves playing a swastika-shaped drinking game and shouting "Heil Hitler."
