'But if you explain why the remarks about the Mexican judge were justifiable I promise not to comment at all.'
It is a huge subject, it will require links etc. Too long to get into. Democrat funding, support, set up, border policy, the Wall etc etc Too long to get into, but you can google it and follow all the links and see why Trump attacked the judge and what was really behind it
He attacked the judge because he plays dirty to get his own way in court. It's not complicated at all.
"In an interview, Mr. Trump said U.S. District Judge Gonzalo Curiel had “an absolute conflict” in presiding over the litigation [civil fraud lawsuits against Trump University] 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."

There. Not so hard.
Also:
"Ronald Rotunda, a professor at Chapman University School of Law in Orange, Calif., noted that whatever Mr. Trump’s grievances, his lawyers haven’t filed any motion asking for the case to be reassigned to a different judge. If Mr. Trump has a problem with the judge, “that’s the legitimate way” to register a complaint, he said. Mr. Trump in the interview said that he may do so."
However, Trump ended up settling out of court for a large percentage of what the plaintiffs were asking for.
