(NBC News) — Two days after a white gunman opened fire and killed 10 Black people at a Buffalo, New York, grocery store, teacher Elizabeth Close began her high school ethnic studies class in Austin, Texas, by reminding her students about a new state law that requires her to provide balanced perspectives on “widely debated and currently controversial issues.”

Close told her students that under the law, one of several recently implemented across the country that limit the ways teachers can discuss racism and current events, she was obligated to inform them that there’s more than one way to view Saturday’s mass shooting. 

On one hand, she explained that authorities are investigating the killings as a racially motivated hate crime carried out by an 18-year-old who reportedly wrote of his belief in a conspiracy theory that white Americans are being “replaced” by people of color through immigration, interracial marriage and integration.

“But I’m also supposed to tell you that that’s just one perspective,” Close recalled telling her students. “Another perspective is that this young man was out defending the world — or his kind — from being taken over.”
