When Trump insults living heroes, his behavior is horrible. But when he insults heroes that are "dancing with the angels" (to quote the wise and recently departed Elijah Cummings), he is despicable. Trump descended towards the bowels of Hell when he insulted the widow and memory of Rep. John Dingell of Michigan. And if you are inclined to snicker at this type of insult, what kind of person are you?
Trump's cruelty is contagious. Inoculate yourself with courage.
