The museum at the former Nazi concentration and extermination camp Auschwitz called a trend on the video-sharing social-networking service TikTok in which young people portray themselves as victims of the Holocaust as “hurtful and offensive.”

“The ‘victims’ trend on TikTok can be hurtful & offensive. Some videos are dangerously close or already beyond the border of trivialization of history,” tweeted the Auschwitz Memorial. “But we should discuss this not to shame & attack young people whose motivation seem very diverse. It’s an educational challenge.”

The tweet included an attached longer statement.

“We have to be very careful in this discussion because the language used—also very often in social media—seems to carry lots of emotions, sometimes very strong,” reads the statement, warning against “vilifying” those who are part of the trend.
