Katy Perry has thrown her full support behind the Muslim American community with a new YouTube video this week called: "Is history repeating itself?"

Using the hashtag #DontNormalizeHate, the American pop star, who >executive produced the clip tells the story of an 89-year-old Japanese-American who was registered and incarcerated along with some 120,000 others during World War II. 

Perry doesn't personally appear in the clip. 

In the video, an actor plays the role Haru Kuromiya, and tells the personal and disturbing story of the injustice committed by the U.S. government against Americans of Japanese ancestry in 1942.

"My entire family was put on a registry," Kuromiya says. "Our constitutional rights were taken away from us."

And then, as Kuromiya looks down in sadness, there's an unexpected twist, reminding us all that Muslims and other minorities could now face the same fate. The video warns against normalizing hate, something many believe U.S. President-elect Trump has done since he launched his political career.

If hate is normalized, just like it was during WW II against the Japanese, history could repeat itself. Already, Trump has called for a Muslim registry, the first step in officially targeting an entire community.

The filmmaker behind the project, Aya Tanimura, has worked with Perry in the past. Both women felt an urgency to raise awareness as Trump is set to take office on Jan. 20.

"Trump has created an atmosphere of fear for Muslim Americans in the United States," Tanimura told the LA Times.

He has also made it easier for people to be racist in the U.S., she added. 

Perry will be joining a mass march on Washington D.C. the day after Trump's election. She will join thousands of other ordinary Americans and celebrities in opposing the new president and his stance on Muslims, women and other minority groups.
