“If you’re not outraged, you’re not paying attention.” That was the last Facebook post of Heather D. Heyer, a 32-year-old woman who went out on Saturday to face down white supremacists in Charlottesville and was killed before the day was done; police said 20-year-old James Alex Fields has been charged with second-degree murder in the death. Ms. Heyer’s death, and the injury of 19 others when Mr. Fields reportedly rammed his car into a group of counterprotesters, was the horrific capstone to a weekend of violence in the Virginia college town.

Outrage is something Donald Trump typically has in no short supply. As Stephen Hayes reminds readers in The Weekly Standard, this president is promiscuous with his denunciations. “Brit Hume is ‘a dope’ and a ‘know-nothing.’ Mika Brzezinski is ‘dumb as a rock’ and ‘crazy.’ Bill and Hillary Clinton were ‘the real predators.’” Trump is always ready to blast those he believes — often wrongly — to be worthy targets.
