Final answer:
The Whitman Massacre was caused by conflicts with local Native American tribes due to resentment and racism. Reverend Perkins believes that these conflicts led to the loss of homeland for the Plains Indians. Evidence from Narcissa Whitman's diaries supports Perkins's argument.
Step-by-step explanation:
The Whitman Massacre was caused by conflicts with local Native American tribes. According to Reverend Perkins, the Native American tribes felt resentment and racism towards the white settlers, which turned into outright hatred. Over time, the Plains Indians lost their homeland due to these conflicts.
Reverend Perkins's point of view is that the Whitman Massacre was a result of the bad feelings and racism on both sides, contributing to the loss of homeland for the Plains Indians.
Evidence from Narcissa Whitman's diaries supports Perkins's argument. Whitman's diaries describe incidents of tension and mistrust between the settlers and Native Americans. The diaries also mention the killing of white settlers and the ensuing retaliation, which aligns with Perkins's view of conflicts between the two groups.
