In countless collisions of color and creed, Donald J. Trump’s name evokes an easily understood message of racial hostility. Defying modern conventions of political civility and language, Mr. Trump has breached the boundaries that have long constrained Americans’ public discussion of race.
Mr. Trump has attacked Mexicans as criminals. He has called for a ban on Muslim immigrants. He has wondered aloud why the United States is not “letting people in from Europe.”
His rallies vibrate with grievances that might otherwise be expressed in private: about “political correctness,” about the ranch house down the street overcrowded with day laborers, and about who is really to blame for the death of a black teenager in Ferguson, Mo. In a country where the wealthiest and most influential citizens are still mostly white, Mr. Trump is voicing the bewilderment and anger of whites who do not feel at all powerful or privileged.
But in doing so, Mr. Trump has also opened the door to assertions of white identity and resentment in a way not seen so broadly in American culture in over half a century, according to those who track patterns of racial tension and antagonism in American life.
