Yes, Motley, we know of these quotes which are well outside the major thrust of  his major  political views , as you would know if you'd read Lincoln's entire collected writings rather than snatch a few out of context quotes.  The South understood, that's why they seceded. 
This is a man whose entire political life was dedicated to ending slavery, and as a practical politician he knew he'd have to get elected to accomplish his goal.  He also realized that while the majority of whites in the north might favor ending slavery, they also had no wish to have  free blacks living  among them with equal rights  either.
This is  a man who, like RFK, kept growing beyond the prejudicial stereotypes of his youth, and who was ultimately embraced by the great  Frederick Douglas.
The attempt to elevate one's modern self  above Lincoln's moral character is pathetic, and reminds me of a local black radical militant who claims the only Republican president he hates more than Trump is Abraham Lincoln.
