Jonathan Weisman writes: A Jewish 17-year-old, inflamed by the Black Lives Matter movement and the cause of L.G.B.T. rights, told me recently there is no anti-Semitism, certainly nothing compared with the prejudices that afflict other minorities. I surprised myself when I recoiled from her words and argued passionately that Jews must never think anti-Semitism has been eradicated. I sounded like my mother.

Just weeks later, I found myself staring down a social-media timeline filled with the raw hate and anti-Semitic tropes that for centuries fueled expulsion, persecution, pogroms and finally genocide.

“I found the Menorah you were looking for,” one correspondent offered with a Trump-triumphant backdrop on his Twitter profile; it was a candelabrum made of the number six million.
