Percentage of Americans who don't know about the Holocaust is "shocking and saddening"

Almost two-thirds of Americans 18-39 didn't know that 6 million Jews were murdered in the Holocaust, according to a survey. From The Guardian:

According to the study of millennial and Gen Z adults aged between 18 and 39, almost half (48%) could not name a single concentration camp or ghetto established during the second world war.

Almost a quarter of respondents (23%) said they believed the Holocaust was a myth, or had been exaggerated, or they weren't sure. One in eight (12%) said they had definitely not heard, or didn't think they had heard, about the Holocaust.

More than half (56%) said they had seen Nazi symbols on their social media platforms and/or in their communities, and almost half (49%) had seen Holocaust denial or distortion posts on social media or elsewhere online.

"The results are both shocking and saddening, and they underscore why we must act now while Holocaust survivors are still with us to voice their stories," said Gideon Taylor, president of the Conference on Jewish Material Claims Against Germany (Claims Conference) which commissioned the survey.
