Why were the teachers encouraged to kill the Indian culture?

Teachers were often encouraged to suppress Indigenous cultures as part of broader assimilation policies aimed at integrating Indigenous peoples into dominant Euro-American cultures. This was particularly evident in residential schools, where Indigenous children were prohibited from speaking their languages or practicing their traditions. Such measures were rooted in a belief that Indigenous cultures were inferior, and the goal was to erase these identities to promote a homogenized national identity. This cultural genocide had devastating effects on Indigenous communities and their heritage.
