Yesterday Peter Baker and Katie Rogers at the Times wrote about Trump’s filthy dehumanizing language.

President Trump has railed against undocumented immigrants in recent days, branding many of them “murderers and thieves” who want to “infest our country.” Not long ago, he referred to them as “animals,” although he insisted he meant only those who join a violent gang.

The president’s unpresidential language has become the standard for some on his team. This week his former campaign manager, Corey Lewandowski, made a mocking noise, “womp womp,” when a liberal strategist raised the case of a 10-year-old girl with Down syndrome separated from her parents at the border.

…

Mr. Trump’s descriptions of those trying to enter the country illegally have been so sharp that critics say they dehumanize people and lump together millions of migrants with the small minority that are violent. This approach traces back to the day Mr. Trump first announced his campaign for president in 2015, when he labeled many Mexican immigrants as “rapists,” a portrayal that drew furious protests.

Mr. Trump recalled that controversy just this week and doubled down on it. “Remember I made that speech and I was badly criticized? ‘Oh, it’s so terrible, what he said,’ ” he said with derision during a speech to the National Federation of Independent Business on Tuesday. “Turned out I was 100 percent right. That’s why I got elected.”

And here we are, trapped in this hell.

He has made insults the core of his presidential messaging. He has called Canada’s prime minister “weak & dishonest.” He has called journalists, lawmakers and political opponents “wacky,” “crazy,” “goofy,” “mentally deranged,” “psycho,” “sleazy” and “corrupt.” He has called some of his own appointees and Republican allies “very bad,” “VERY weak,” “failed” and “lightweight.”

Because that’s who he is – abusive. He’s an abusive sadistic bully, who enjoys being an abusive sadistic bully, and is simply loving being it on the world stage.

“Only Trump can get away with being Trump,” said Jennifer Mercieca, an associate professor at Texas A&M University who has studied his language closely over the last three years.

“Any time that other people have tried to use ad hominem attacks or swear or whatever, it rings false,” she said. “And other politicians tend to have more shame, so when they’re criticized they fold. And as you know, Trump doesn’t do that. And so because he refuses to be shamed, he can get away with sort of saying anything.”

In other words only Trump has no conscience and no empathy – only Trump is a psychopath.
