Abortion, free-market Capitalism and especially Trump are in no way shape or form "traditional systematic theology." All of these things have been embraced by (protestant) churches only in the last generation or two at most (or the last six or so years in the case of Trump). I would argue their embrace represents the church melding to contemporary trends, certainly not the other way around. And no, this is not an argument for unlimited abortion or socialism. I recognize that you tried to qualify the various examples by using the word "SOME", but this is a point of contention over the misuse of the term "traditional" before mentioning things that are certainly not traditional in Christianity at large.
