Howard Zinn is a disgrace! He's not an educator. He's an indoctrinator!
I would expect a religious zealot to know a thing or two about indoctrination.
Howard Zinn did not indoctrinate, he challenged the indoctrinated to view history from a different perspective. That of the historically disadvantaged. A worthy exercise that apparently scares people. Wonder why.
Zinn provided Marxist agitprop. His "history" was fabricated horseshit designed to cast America and especially capitalism is a villainous role. It is the mirror opposite of history that shows America as incapable of any wrong. Both are the opposite of critical thought.
Critical thinking is how one should attempt to process the information presented from both perspectives. Banning the book is just an attempt to silence one perspective because it is uncomfortable and denies the students the opportunity to develop critical thinking skills. Banning the book is in essence an attempt to indoctrinate.
No. Using an insanely biased book is a crappy idea.
Using that as a textbook, there are no "both" perspectives. There is only Zinn's perspective. Using only that book is denying students the opportunity to develop critical thinking skills.
2 options to alleviate the problem:
Use 1 unbiased textbook. Or..
Use Zinn's book and another one as a balance.
Which one is more economical?
