The incident took place last year when the actor, 70, was vacationing with his family in Southern Europe.
His 14-year-old son was confronted with anti-Semitism when he was at the swimming pool and a man insulted him because he was wearing a Star of David.
Following the discussion with that man, Douglas concluded that his son had been insulted simply because he was Jewish.
After that, he explained to his son that he had just experienced his “first taste of anti-Semitism.”
Also, Douglas said that just like with his children, his father Kirk Douglas is Jewish, and his mother, Diana Dill, is not. The actor reconnected with the religion a few years ago, when his son Dylan “developed a deep connection to Judaism.”
