Attorney Alan Dershowitz in Washington, Jan. 29, 2020. Photo: Mario Tama/Getty Images Everything Alan Dershowitz writes about George Soros may be true (“Elon Musk Is Right About George Soros—and Not Anti-Semitic,” op-ed, May 22), but those truths shouldn’t permit Mr. Musk to malign Mr. Soros by referring to him as Magneto, the Holocaust survivor and mutant from the comics, and to write, “Soros hates humanity.” Attacking Messrs. Soros, Musk or Dershowitz for their ideas is everyone’s right. Linking those attacks to religion, race or ethnicity is another story.
