Stereotypes are often addressed in Butler’s novels, including Kindred. In Kindred, how does the author, with her various characterizations, reveal the origins of stereotypes? How does she deflate them?

Octavia Butler's Kindred features a protagonist, Dana, who is a black woman in the 1970s in California. Dana gets mysteriously, and without much warning, pulled back into the antebellum South to learn about her family origins.
As she is transported to the South, Dana is assumed to be a slave. She must learn to adjust to life on the plantation despite always having been free in her "real life" in the 1970s. During this time, she of course learns about racism and comes face-to-face with the brutal treatment of her ancestors, including a foremother named Alice. Over the course of the novel, Dana learns that the plantation master, Rufus, a boy she once saved as a child in one of her trips to the past, is also her ancestor. Dana learns the dark truth about sexual politics on the plantation when Rufus tries to rape her near the end of the novel, after repeatedly taking advantage of Alice as well. The antebellum South chapters demonstrate to Dana the extent to which black women were abused under the plantation system.
Meanwhile, in modern-day America, Dana is married to a white man named Kevin. Their relationship is based on love, respect, and mutual interests. While they have freely chosen to be together, Dana's trips to the past complicate the way she views her relationship with Kevin. When Kevin eventually travels with her to the plantation, their vast differences in the antebellum South are thrown into stark relief: Kevin is assumed to be a powerful master. In their modern-day lives, Kevin and Dana see themselves as equals. This contrast in their roles could be said to "deflate" the stereotypes, or at least to show the way race relations and sexual politics have evolved in the 100+ years since abolition.
