DUESSELDORF, Germany (AP) — Herbert Rubinstein was 5 years old when he and his mother where taken from the Jewish ghetto of Chernivtsi and put on a cramped cattle wagon waiting to take them to their deaths. It was 1941, and Romanians collaborating with Germany’s Nazis were rounding up tens of thousands of Jews from his hometown in what is now southwestern Ukraine.

“It was nothing but a miracle that we survived,” Rubinstein told The Associated Press during a recent interview at his apartment in the western German city of Duesseldorf.

The 88-year-old Holocaust survivor is participating in a new digital campaign called #CancelHate. It was launched Thursday by the New York-based Conference on Jewish Material Claims Against Germany, also referred to as the Claims Conference.

It features videos of survivors from around the globe reading Holocaust denial posts from different social media platforms. Each post illustrates how denial and distortion can not only rewrite history but perpetuate antisemitic tropes and spread hate.
