This week’s mass shooting at the Waffle House in Nashville was, in most ways, typical: The perpetrator was a white man with a history of mental health problems and a small arsenal.

What marked it as unique was that the shooter was disarmed by an unarmed African-American man, who saved an unknown number of his fellow citizens from being slaughtered.

Honestly, the races of these men shouldn’t matter.

But they do. And they do because the very people who stand in the way of sensible gun control legislation in America — which is to say, gun manufacturers and their Republican servants in Congress — have pursued a politics explicitly based on race.

In fact, the modern GOP, along with the for-profit demagogues of the conservative media, have created an entire mythology around race and violence in this country.

In this mythology — which I call Fear of a Brown Planet — America’s white population is perpetually under siege by the dark other.

Mexican rapists and gang members are pouring over the border to stalk white Americans. Muslims lurk in sleeper cells in American cities, itching to commit a terrorist assault on whites. African-American thugs lie in wait for any hapless white person foolish enough to wander into their “hood.”

For years, the GOP dog whistled these racialized appeals. Donald Trump wolf-whistled his racism. These smears weren’t just an unfortunate feature of his electoral strategy; they were integral to his appeal. They were what caused many Republicans to embrace a politics of racial resentment over one of economic uplift.

He ran as a law-and-order candidate who advocated getting tough on these dark others. How? By creating a national registry, a travel ban, by urging cops to rough them up.

But our latest mass shooting highlights a galling irony: This racist mythology has created a safe space for the demographic group that actually commits the majority of these atrocities -- troubled white men with guns.

If that sounds outrageous, just imagine how conservative pundits and politicians would have reacted if the man who stockpiled an arsenal in Las Vegas and terrorized concert goers was an undocumented immigrant? Or if the “troubled young man” who murdered 20 kindergarteners in Newtown, Connecticut, was an African-American from the “inner city” of New Haven? Or if the man who blew up a federal building in Oklahoma City, killing 168 people, was a Muslim?

Better yet, what if a Muslim (or an undocumented immigrant, or an African-American) carried out all these attacks? What if individuals from this demographic group displayed a consistent pattern of targeting innocent civilians with weapons of war?

What would have happened, almost inevitably, is that right-wing pundits and politicians would have exploited these crimes to propose various draconian measures against that demographic group intended to keep “innocent, law-abiding Americans” (meaning white Americans) safe.

I say this to make a larger point: that our view of mass shootings is already occluded by systemic racism.

After all, if our perspective were entirely color blind, politicians and pundits who truly cared about keeping Americans safe would advocate measures intended to crack down on the demographic group that most often commits these crimes.
