That was exactly the point. Many of the "Lincoln-worship" crowd deny his support of colonization. Read the excuses offered up by your counterparts. An objective review of his policies and speeches leads to an inevitable conclusion, of you which you recognize.
I am less well researched about Davis' position on the subject. Perhaps the bottom-line is both men held similar views.
Both men did not. Lincoln was unalterably opposed to slavery, Davis was a strong supporter of slavery. Lincoln believed that black men should be free, Davis believed that blacks were suited for slavery and nothing else. Lincoln believed that free blacks should enjoy many of the same rights as whites, Davis did not. There is a vast difference between the two viewpoints.
