They understand what they’re doing just fine. It’s a choice to deride doing the right thing as “virtue signaling” and embrace evil.

For example, Trump has been seen to read just one book:

Last April, perhaps in a surge of Czech nationalism, Ivana Trump told her lawyer Michael Kennedy that from time to time her husband reads a book of Hitler’s collected speeches, My New Order, which he keeps in a cabinet by his bed. Kennedy now guards a copy of My New Order in a closet at his office, as if it were a grenade. Hitler’s speeches, from his earliest days up through the Phony War of 1939, reveal his extraordinary ability as a master propagandist.

“Did your cousin John give you the Hitler speeches?” I asked Trump.

Trump hesitated. “Who told you that?”

“I don’t remember,” I said.

“Actually, it was my friend Marty Davis from Paramount who gave me a copy of Mein Kampf, and he’s a Jew.” (“I did give him a book about Hitler,” Marty Davis said. “But it was My New Order, Hitler’s speeches, not Mein Kampf. I thought he would find it interesting. I am his friend, but I’m not Jewish.”)

Later, Trump returned to this subject. “If I had these speeches, and I am not saying that I do, I would never read them.”
