That part of your post I can agree with.
That is how I came to be aware of the other side of the story.
My comments had more to do with the "approved" versions of events that are taught to almost all school children, most of whom go on to believe it for the rest of their lives.
Going back to previous posts -
In schoolroom discussions of The Emancipation Proclamation most children are taught the cleaned up, dumbed down slogan "Lincoln Freed The Slaves".
There is usually little if any mention of the well documented fact that Lincoln cynically declared freedom for the slaves only in the southern states, areas he didn't control, that were still controlled by the Confederacy. He did not apply the Emancipation to slaves in areas where his word would actually have immediately freed some slaves. Such as those in the border slave states and those in southern areas under Union control.
Check 'DiogenesLamp' Post #97 on this thread for for a useful historical reference on this point.
He did not because he could not.
