Earlier this year, a man by the name of Robert Aaron Long, went on a killing spree at 3 spas in Atlanta, GA, killing multiple people of Asian descent. According to the New York Times, "The man who police say went on a rampage at three spas in the Atlanta area, killing eight people, was charged on Wednesday with eight counts of murder in connection with the attacks. The brazen shootings, which took the lives of six women of Asian descent, stirred considerable outrage and fear in the Asian-American community. Investigators said they had not ruled out bias as a motivating factor even as the suspect denied such racial animus once in custody. The suspect told the police that he had a “sexual addiction” and had carried out the shootings at the massage parlors to eliminate his “temptation,” the authorities said on Wednesday. He also said that he had frequented massage parlors in the past and launched the attacks as a form of vengeance. All but one of the victims were women, the police said"

After this event, there were protests, more killings, etc... towards Asian-Americans. It was all over the news, a lot of Asian-Americans were scared, and there was a lot of violence and hatred to start yet another movement against Discrimination, this one being Stop AAPI Hate, a.k.a Stop Asian-American and Pacific Islander Hate.
This is similar to the books, as it shows the clear effect discrimination has on people in the minority group, and what can happen in the aftermath of it.
The type of Discrimination in this are cultural, as it was against Asian-Americans. Half of the people dead were found ethnic Koreans, and the rest were not identified immediately.
