Find me all the public schools that do not teach American history, or teach American history while omitting the Civil War.
All of them. They teach revisionist crap, and a kindergarten version of that. Howard Zinn's nonsense is the primary model.
You're referring to this, for example?
How Texas is whitewashing Civil War history
Nope. That's not revision. Slavery was a catalyst in a fight over state's rights, not the primary issue.
Do you think that the fact that the election of an abolitionist president and the states immediately leaving the union is an indication that yeah, slavery was the primary cause?
Lincoln was not an abolitionist, Lincoln offered command of the Union Army to Robert E. Lee first, ahead of anybody else, along with offers to many southern officers in lower positions as well, Lincoln and the Republicans' platform was aimed at keeping
all black people out of the new territories, period, and Illinois and other mid-western states passed tougher Black Codes than they already had to begin with throughout the 1850's, just for starters, and in those states the North 'freed', blacks were herded into 'property camps' and left to die by the hundreds of thousands instead of being allowed to flee north, and in other states Lincoln ordered the 'freed' slaves to stay confined on their plantations and not be allowed to leave without written permission from their new masters; he also dictated their pay: $2 a month.
What CArbineer is whining about is Texas schoolbook reviewers insisting on real history being put in history books, and throwing out the lying nonsense his ilk wants in the books.
