Sometimes, knowing when it’s appropriate to be respectful is one of the toughest things citizens encounter. Whether it’s screaming profanity during the national anthem at a hockey game or yelling in a moment of silence, people seem to have a hard time recognizing when doing something is okay.

That’s especially the case, apparently with Pokémon GO players. The mobile game is being played everywhere. In schools, at police stations, in urban centers and along rural rivers. Pokémon GO is even being played in the Holocaust Museum.

“A living memorial to the Holocaust, the United States Holocaust Memorial Museum inspires citizens and leaders worldwide to confront hatred, prevent genocide, and promote human dignity.” That comes from the museum’s official About pagePokémon GO players seem oblivious to all that serious business, instead using the site’s multiple PokéStops (something automatically generated, not signed up for) to score items.

The Washington Post spoke with Museum Communications Director Andrew Hollinger about their stance on playing Pokémon GO within.

“Playing the game is not appropriate in the museum, which is a memorial to the victims of Nazism…We are trying to find out if we can get the museum excluded from the game.”

College campuses, shopping districts, national parks and even museums with lighter subjects are all perfect for Pokémon GO, I’d argue. The business and monuments might even do well for themselves by embracing the game and actively promoting their PokéStops.

The Holocaust Museum? Put your phone down or leave.
