Let's start here: https://www.yahoo.com/news/m/8917fa7f-9aef-3651-80ec-f6e4b8e73bd8/ss_censoring-howard-zinn-and.html
There have been revisionists in every nation on the planet who would change the facts of history to suit their own interests. The most prominent textual changes have probably been in religious books....the Bible comes to mind. But the history of the Americas has been under assault ever since the first white man set foot on these shores, decided this was an uncivilized land, and claimed it all in the name of some foreign power.
Howard Zinn is famous, or infamous, depending on your point of view. Needless to say he will not be celebrated as a great scholar in Arkansas any time soon, but what do they know? Radical thoughts about American history beyond the flag waving apple pie bunch of conservatives means his latest book had to be banned.
In all honesty, I have not read this book, yet. Needless to say it will not be high on the list of acquisitions my local library will order this year. But it is available from Amazon at a reasonable price and I am awaiting delivery. A Peoples History of the United States, sounds like a good read to me.
So read the article and try to see how the contents might fit into your way of thinking. I will read the book and get back to you here once that is accomplished. I love a good story, especially when someone digs thru the American trash bin to write it. I don't doubt the residents of Arkansas will be thrilled to know their state is protecting them from certain knowledge. I intend to read and find out what they don't know, evaluate the words in the book and compare them to what I already know. Arkansas won't find out until Breitbart News tells them what to think. Sad.
