The problem comes in that there's no clean way to promote a tainted subject. We aren't out here talking about the (VERY) minor positive qualities in Hitler's pre-politics paintings, or whether Ronald Reagan had decent acting chops.

There are plenty of other, less-massively-problematic comedians, artists, politicians, actors, and other public figures to promote and laud the work of that we really can just set aside the possibly decent contributions of otherwise bad people. It just doesn't matter enough. Find someone cool who did a good thing and talk about that instead.
