I don't think it's a tangent. Part of explaining liberal shock in 2016 is understanding that the average liberal has an exceedingly selective view of decency, a point underscored by recent efforts to rehabilitate Dick Cheney and, over the years, any number of detestable Republicans who just happened to think Trump too gauche and too dumb to elect. Back in the good ol' days, when the Republican establishment wanted to unnecessarily murder hundreds of thousands of people, they had the common decency to couch it in rhetoric of freedom and democracy, to win Democratic support, and to make it sound intellectually and morally respectable.
