Honestly, I didn't take it that way at all. I read it and understood it literally, and immediately got PDJT's meaning.
I don't think too many people (who aren't already deranged) will read it as you say. Of course the deranged TDS people will go nonlinear if PDJT says "good morning." They'll hear "Ein Volk, ein Reich, ein Führer!"
It’s not the already-deranged people who read it as much as the already-deranged people who wrote it.
No doubt in my mind that CNN wanted their deranged audience of headline-skimmers to think Trump was advocating violence.
I’m afraid I thought that was the intended inference of the headline. I didn’t for a moment think it was true though.
My cynicism of the press is only exceeded by their mendacity.
