Well, if Lincoln where shown to have mowed down a girl scout troop on the steps of the whitehouse with a machine gun you would make excuses for him, so you’re not much of a reliable critic of any books critical of him.
Wasn’t that among the many spurious claims that DiLorenzo made?
And you no doubt already believe that Lincoln gunned down a Girl Scout troop on the steps of the White House, and can no doubt point to half a dozen Lost Cause websites that detail it, so I'd say your no less biased in your way than I am in mine.
