 Partly, it's their basic instinct to demonize Trump at every turn, in every situation, reflexively, no matter what happens. We know that. But at a deeper level, I think these people can't wrap their minds around the fact that Trump responded with such dignity and courage in such a harrowing circumstance. Because they know that if they were in his shoes, if someone shot at them, they would crumple into a ball. They would hyperventilate, cry uncontrollably. They cannot accept that anyone could respond differently, least of all Donald Trump.
