It’s getting hard to parody real life.

This article is more in-depth than most stories I found, which are usually focused on the political books most recently pulled (see the above posts), or the authors’ own niche interests (such as Holocaust denial and white identitarianism), and not on the censoring process itself.

One of the stealth techniques for suppressing something without actually banning it from the Amazon website is to prohibit ads or promotions.

“Is Amazon Allowed to Censor Conservative Books?
From J.K. Rowling to Josh Hawley, writers with unpopular beliefs are under siege. Now Amazon is on the battlefield
Publishers once wanted conservative books because they make money, but they’re pulling back at the first whiff of controversy”

I had the courage to try out some of Zinn’s work in the classroom after reading the intro of A Young People’s History of the United States, particularly this quote: “It seems to me it is wrong to treat young readers as if they are not mature enough to look at their nation’s policies honestly. Yes, it’s a matter of being honest. Just as we must, as individuals, be honest about our own failures in order to correct them, it seems to me that we must do the same when evaluating our national policies.”

A fine platitude from Zinn, and very true — but he was not then, and apparently was not later (he died January 27, 2010), honest about either American history or his own failures.
And the Democrats who love him so much are absolutely dishonest about evaluating our national policies (they don’t evaluate anything in the usual meaning, they just emote and posture).

Grabar also reveals Zinn’s bag of dishonest rhetorical tricks: his slavish reliance on partisan history, explicit rejection of historical balance, and selective quotation of sources to make them say the exact opposite of what their authors intended. If you care about America’s past—and our future—you need this book.

Frankly, I’m surprised Amazon sells it.
I think they got slapped down not long ago for deep-sixing conservative works, and discovered that dissing half the country can lose a lot of customers.

Or maybe they are just being more surreptitious about their proclivities.
This is what they were doing in 2012; don’t know if they’ve changed since then or are just hiding their procedures better.

But then, following your own procedures can get dicey when they’re duplicitous to start with.

Don’t know why. Do know what you said is largely nonsense, so it should not be taught.
