“Walker began to leave, followed by McPherson’s comment that stereotypes are important when they are used in the right way. It brings the reader into something they know, but from there they must be taught the truth and reality.”

With your writing, there were only couple comma errors, one place where you might have used a colon, and maybe one typo: “throught” . Otherwise, you express yourself and Walker’s argument pretty clearly.

Your identification of parallelism is particularly keen, and I would ask you to think about what rhetorical effect this strategy has on us as readers. What differences in character does this direct comparison evoke? For what purpose?

Nice work, nice reading, nice beginning.
