How vulgar and spiritually grotesque is Squirrel-Hair?

This vulgar and spiritually grotesque:

The Wall Street Journal ($) has just released an interview with Donald Trump in which Trump explains his repeated and continued attacks on Gonzalo Curiel, the judge assigned to the Trump University case. Curiel’s decision to release records related to the case in response to a public interest request filed by the Washington Post has clearly infuriated Trump and imperiled his general election campaign.

In a rambling tirade against the judge, delivered earlier this week in his back yard of San Diego, Trump said, among other things, that Curiel was “a Mexican, we think.” (Curiel, as it happens, is from the Chicago area, but his parents are of Mexican heritage.) The WSJ finally got around to asking Trump the question that should have been asked from the first moment he mentioned the judge’s ethnicity, which was actually a couple months ago when Curiel refused to dismiss the case on summary judgment. That question, of course, is “Why would you bring up the judge’s ethnicity at all?”

Trump’s answer was, shall we say, revealing:

In an interview, Mr. Trump said U.S. District Judge Gonzalo Curiel had “an absolute conflict” in presiding over the litigation given that he was “of Mexican heritage” and a member of a Latino lawyers’ association. Mr. Trump said the background of the judge, who was born in Indiana to Mexican immigrants, was relevant because of his campaign stance against illegal immigration and his pledge to seal the southern U.S. border. “I’m building a wall. It’s an inherent conflict of interest,” Mr. Trump said.

Think about what Trump is saying for a minute. Forget that Trump himself repeatedly bragged on the primary campaign trail that he would win the Hispanic vote and focus on what he is now saying: he is saying that no Hispanic person on earth can be trusted to give him a fair hearing. He is saying that no one – even a Mexican born in America – can be trusted rule impartially in accordance with the law simply because of Trump’s stance on whether there ought to be a wall on the Southern border.

Keep in mind, Curiel himself is not an illegal immigrant, or even an immigrant. I have no idea whether his parents were even immigrants or illegal immigrants. They are of Mexican heritage, therefore he cannot be trusted to pass judgment on Trump, who supports a wall on the Mexican border.

Does this sound like a guy who will tolerate differing policy views from leaders of Congress if he's elected president? Is this how he's going to "negotiate" those international trade deals?
