A new report by the Anti-Defamation League is sounding the alarms about a rise in antisemitic beliefs among Americans.

The survey found that the number of people in the country harboring extensive antisemitic prejudice has doubled since 2019 - the highest level in decades.

Among the findings were 1 in 3 respondents agreed that "Jews do not share my values" and around 26% agreed that "Jews have too much power in the business world."

Holocaust survivor Alex Konstantyn, of East Meadow, says the rise in these beliefs is alarming.

At the age of 4, he and his family fled the Nazis and went into hiding for two years in Poland. Over 80 years later, Konstantyn remembers the terror from being the target of hate.

"It is scary because if we are not careful, history will repeat itself," Konstantyn says.

He has made it his mission to fight antisemitism through education.

Konstantyn and other Holocaust survivors are speakers at the Holocaust Memorial and Tolerance Center. They share their stories with school groups to teach the cost of hatred.

"I see an impact," Konstantyn says. "When I talk, they listen. They are still young enough not to be tainted by antisemitism."

Dana Arschin, of the Holocaust Memorial and Tolerance Center, says they educated 50,000 people in 2022.
