And if the teacher said "This book is about persuasive writing style" we would not have this conversation. She specifically gave the book because it describes racism, she did not even mentioned the style (at least per article).
I want my child to learn about racism from the teacher who is trained to talk about this topic, who has specific class for that, and bring it as a part of complex social problems that exist, not from activist in literature class, who suppose to teach literature.
I do not understand your question. Are you still talking about Critical Race Theory, or switched to Cathode Ray Tube?
