You would think some places are so sacred that no one would dare take a “fun” photo there, but I guess we can all be surprised by how insensitive people are.

It is frankly mind-blowing to think that anyone would visit the Auschwitz concentration camp in Poland and think to take playful photos at a site where over 1 million people were murdered. I can tell you from my personal experience, visiting Auschwitz in 2003 was one of the most sobering days of my entire life.

But, due to the fact that visitors have been posting inappropriate photos from Auschwitz to social media, the memorial site had to put a tweet out admonishing that kind of ridiculous behavior.

The infamous train tracks of Auschwitz carried untold numbers of people to their deaths, and to see people acting this way has upset many. People on Twitter were taken aback by the trend and weighed in with their own opinions.

The Auschwitz Memorial later added these tweets.

If you’re visiting a place where unfathomable atrocities took place, have some respect and be aware enough not to take cute selfies. Thank you.
