The issue of race has scarred the entirety of U.S. history. Although sometimes overshadowed by the arguably more deep-seated issue of class, the racial divide is a festering wound that decent Americans, including politicians, genuinely want to heal.

Decency and politics have a tenuous relationship, but this year, one candidate has exacerbated racial tensions in a way not seen since the days of segregationist George Wallace and Richard Nixon’s polarizing vice president, Spiro Agnew. Donald Trump, through his outbursts and incendiary rhetoric, opened the door to a new period of even greater racial antagonism.

Trump promises to “make America great again,” but his divisive approach leaves us both weaker and even more afflicted with racial identity politics. Just as neo-Nazis and old-style racists have rallied to his cause, Trump’s intemperance also has energized ethnic nationalists, particularly in Hispanic communities. Among America’s growing Muslim population, perhaps no one has served as a better recruiter for Islamists, who agree with him that their religion and culture is anathema to America. The triumph of Brexit -- in part driven by immigration -- may encourage this further.

Not all the blame for America’s racial discord falls to Trump, of course. Well before his rise to political prominence, Americans had grown pessimistic about race relations, which constitutes something of a failure by an administration that once promised greater racial unity. The president and Hillary Clinton, who have used racial politics to motivate minorities against the perceived racism of middle and working class whites, share responsibility for the deterioration. And liberal media, academics and elected officials can’t be particularly proud of their records of promoting tolerance and multiculturalism.

White America Betrayed?

In recent years, large swaths of working whites, like their British counterparts, have seen their jobs disappear and old social orders upended, fueling anger and a general sense of loss, reflected in rapidly rising morbidity and suicide rates. As Pittsburgh psychologist Kenneth Thompson puts it: “Their social habitat is strained, and the strain is showing up in a looming body count.”

Trump has exploited their anger by turning it on immigrants, characterizing Mexicans as rapists and calling for border walls, immigration bans and tougher trade deals. However cruel and misguided, Trump’s racial divisiveness resonates with these blue-collar whites, as well as among some more affluent middle-class whites.

In reality, Trump is not a classic racist, but rather an ugly opportunist willing to use ethnic divides for his own benefit. He’s been compared to Adolph Hitler, a monster whose philosophy revolved around race, but Trump has no real theory that extends beyond self-glorification, resentment, and attracting the fetching female; “The Art of the Deal” is not “Mein Kampf.”

Trump will play the race card as a way to satisfy his narcissistic need for enthusiastic admirers. This does not mean his approach does not echo the racism of the past. His claim of bias by a U.S.-born judge of Mexican descent, as well as his suggestions that Muslim jurists are incapable of ruling independently, recall the worst of the pre-Civil Rights South. His proposals to ban Muslim immigrants in general recall approaches in the late 19th and early 20th centuries which targeted Chinese, Japanese and, ultimately eastern and southern Europeans.

Other Negative Forces

Progressives – including the media claque and academic elites -- have shown little sympathy for the white working class and have been dismissive of its embrace of Trump’s candidacy, as characterized by Salon’s recent description: “White America’s sad last stand.”

Instead of trying to understand the deep frustrations of the white middle class, it’s not unusual for progressives to express solidarity with racial minorities and condemn white privilege.

Clinton takes it a step further, stoking minority fear-mongers to generate badly need enthusiasm. Accused of using “dog whistles” to attract racists against candidate Obama in 2008, Clinton now courts racial nationalists, including some in the Black Lives Matter movement, race-baiter supremo Al Sharpton, and La Raza.

Interestingly, the fury against white “racism” is most fully throated and often most violent in white, deep-blue bastions such as Portland, Seattle, San Francisco and Boston. It’s in these cities, ironically, where minorities increasingly are victims of gentrification, forced out of their neighborhoods to make way for affluent whites.

At the same time, liberal cities’ planning, energy and environmental policies do not improve life for the working- and middle-class populations, including many minorities. Yet while more highly paid blue-collar jobs disappear, working-class communities frequently are the ones absorbing large numbers of undocumented immigrants. The affluent, “enlightened” liberals in places like Chicago’s Gold Coast, west Los Angeles and the upper east side of Manhattan may get their servants from these populations, but rarely are they neighbors or competitors in the job market.

These are fruits of America’s failed immigration system, an issue that even Latinos in this country are eager to resolve. Had Trump not crossed so many lines of decency, he might have seized the day and turned immigration policy into a huge plus, earning the support of the solid majority of Americans who agree that the border needs to be tightened.

But by painting Latinos as drug dealers and criminals and suggesting that Muslims, per se, represent a security danger, Trump has made himself the issue and squandered the opportunity.

Trump’s willingness to “tell it like it is” may have won over some segments of the population, but it’s fanciful to believe, as some right-wingers do, that it can carry him to the White House. His assaults on issues such as illegal immigration and the need to closely monitor potential terrorists may resonate, but his stridency, and lack of respect for basic decencies, have alienated much of the population.

Multiculturalism of the Streets

The good news is that while race seems to have paralyzed politics, society is becoming more integrated. Once lily-white suburbs are increasingly multi-racial, even as some core cities become less diverse. What the Mexican journalist Sergio Munoz once called “the multiculturalism of the streets” is thriving, even as politicians promote division.

A key indicator is the rising rate of racial intermarriage. Pew surveys show that mixed-race couples account for 15 percent of marriages, including nearly 10 percent of white marriages, 17 percent of black, 26 percent of Hispanic and 28 percent of Asian marriages. This is sure to blur racial distinctions in the decades ahead. If you live in a diverse region like Southern California, you see this mixed-race reality all the time -- at grade school graduations, Angels games, in restaurants and Fourth of July parades. This is the new America.

This 21st century nation-of-immigrants picture is unlikely to stir the soul of the celebrity billionaire with a taste for 24-karat gold plating on everything from his seat belts to his sinks. Trump is in it only to win, because winning is everything to him. The problem is Trump’s vanity campaign will probably cost Republicans the White House, leaving America bluer, more regulated and less responsive to the needs of white workers. In this sense, Trumpism represents something akin to Marx’s “opium of the masses,” an emotional balm that only provides temporary relief.

Clinton’s embrace of racial nationalists, on the other hand, forces her to lead from a position that is fundamentally partisan and mean-spirited. But it is Trump who threatens racial progress more directly, in a more irresponsible and inflammatory fashion. In this case, at least, the despicable is far preferable to the dangerous.

The best hope here is that, once this awful and dangerous lout is dismissed from the national scene, our racial wounds will be allowed again to heal. The spark for this will not come from the venal political and media class, but through day-to-day interactions in the communities we increasingly share.
