Germán sounds like a giant bully to me. Yes, Cluess was rude and unnecessarily combative (not the best way to have one's message received), but nothing she said was racist or "oppressive." What saddens me the most is that Cluess apologized. It will be a tragedy if we let these critical race theory throw out the entire canon instead of teaching children how to read critically and think for themselves. There are vast riches of humanity, reason, and thought in those old books, and teaching children that they're too fragile to be able to read differing and even offensive points of view is a terrible idea. We must teach them how to develop their own judgment so that no matter what ideas they encounter they can form their own response based on reason, facts, and experience.
My children will read the Classics regardless of what's going on in the school system, but to deprive schoolkids of access to some of the important writers of the past means that many of them will never be exposed to the last 300 years of ideas.
