This is honestly what Movies.com thinks the Lincoln poster is saying

Hopefully they won't bother mentioning in the film those nasty accusations that if Abe hadn't been killed by Booth, he (Abe, I mean) would have died soon due to complications resulting from some strange STD that he had miraculously developed within his body earlier.

The whole 'colour blind' idea doesn't even really stand up, does it? "Lincoln wants you to forget about slavery by looking at everything in BLACK and WHITE"
