I suppose the reason I said "leftists" was because the article was written from a perspective I would define as "leftist", and I was taking issue with the article and some of the presuppositions and premises that leftist thought holds. Part of that is the moral relativism that I see eating the heart of civilization, decimating self-identity, and destroying social fabrics. I'm fine with you disagreeing with me on these things, and I don't want to start another argument, but I am trying to answer your question honestly. I don't think Christians should oppose Trump. It's more nuanced than that. I think Hillary Clinton would have been equally un-Christian of a leader in the White House, that being said. I just don't think I'd prescribe Christians either 100% supporting or 100% opposing Trump - things are more nuanced than that.
Since you brought up archetypes, I'm kinda curious who you mean by "Leftists". For what it is worth, I don't know of her (heck, I haven't even read the piece) but I checked out the author's twitter page, and she is followed by accounts I'd consider Leftist (Kshama Sawant, AK Press, Haymarket Books, Verso Books).
