(CNN) Health officials issue public warnings about spikes in everything from the flu to the measles. But there is one contagion authorities are ignoring:

We're facing another outbreak of "whitesplaining."

The implication: These white people know more about how racism operates than those who've struggled against it for much of their lives.

To become a victim of "whitesplaining" is infuriating. Imagine a plumber trying to tell a pilot how to land a plane or a man trying to tell a mother what it feels like to give birth. Fortunately, whitesplaining is not a silent epidemic. Some of the biggest headlines about race recently have featured some form of whitesplaining:

• Republican lawmakers in Wisconsin engaged in legislative whitesplaining when they blocked their black Democratic counterparts from honoring a former NFL quarterback during Black History Month because he was "too controversial."

• Virginia's Democratic Gov. Ralph Northam whitesplained when he referred to slaves as "indentured servants from Africa," after having to apologize for a yearbook photo of a person in blackface while admitting he once wore blackface at a Michael Jackson dance contest.

• Conservative commentators whitesplained when they dismissed critics who accused President Trump of making light of the "Trail of Tears," one of the most tragic episodes in Native American history, in a tweet aimed at Sen. Elizabeth Warren.

• Former Starbucks CEO Howard Schultz served up a grande version of whitesplainers' jargon when he told a CNN town hall, "I honestly don't see color."

• And actor Liam Neeson could have gotten an award for Best Whitesplaining Performance by a Man in Denial after he told a black journalist he wasn't racist after confessing to roaming the streets looking for a random "black bastard" to kill after a woman he knew said she had been raped by a black man.

There are different strains of whitesplaining, but what unites them all is the belief that white people are more qualified to decide what's racist and what's not, says Jonathan Walton, author of "Twelve Lies That Hold America Captive."

White men in particular have felt free to define standards of beauty, goodness and even freedom for all people, Walton says, "so why not define racism as well."

"The power to define is reserved for white people, which is the crux of whitesplaining," he says.

Phrases that trigger whitesplaining

The situation this week in Wisconsin offers a good example of how quickly whitesplaining can spread.

Some black Democratic lawmakers wanted to honor former NFL quarterback Colin Kaepernick for his protests against police brutality as part of Black History Month. But some white Republican lawmakers decided that they should determine which black people were worthy of being honored -- not black lawmakers.

They said the only black heroes who should be celebrated during Black History Month were those who wouldn't divide people.

One Republican lawmaker didn't even bother to "whitesplain." State Rep. Jim Steineke said he opposed including Kaepernick's name for "obvious reasons."

The symptoms of whitesplaining are so subtle that sometimes even well-meaning white people are not aware they've been infected. It's similar to situations where men are often surprised to learn how much they talk over women.

Maisha Z. Johnson, author of an essay entitled, "6 Ways Well-Intentioned People Whitesplain Racism (And Why They Need To Stop)," identifies telltale phrases that signal someone is about to whitesplain:

"But I'm not a racist."

"You're being so divisive."

And one of her favorites: You're getting "emotional."

"If you try to tell me I shouldn't be emotional about a racial justice issue, then I already know you don't understand that issue," she writes. "Because emotion is a natural response to oppression -- and having someone judge how I feel about it just makes me feel worse."

Johnson says she often encounters white people who offer corrections to the essays she writes about her personal experiences with race.

"It's absurd," she told CNN from her home in Oakland, California. "I would not presume to explain science to a scientist. But for whatever reason when it comes to race there is this idea that someone with zero experience with something I've lived with can explain this to me."

The history of whitesplaining

Whitesplaining isn't anything new. Johnson's white critics are carrying on a tradition almost as old as the nation's founding.

White people have been assuming that people of color are not reliable witnesses about their own experiences for centuries.

Even slavery was whitesplained at the time.

In his essay , "White Ignorance," the philosopher Charles W. Mills said that in the 19th century, enslaved Africans weren't seen as having the authority or credibility to describe their experiences. Slave narratives had to have white authenticators to confirm that what a slave said about slavery was indeed true.

Many whites didn't want to know what blacks were really experiencing, Mills writes. He quotes a black woman who grew up during the Jim Crow era:

"My problems started when I began to comment on what I saw. ... I insisted on being accurate. But the world I was born into didn't want that. Indeed, its very survival depended on not knowing, not seeing -- and certainly, not saying anything at all about what it was really like."

Black people, though, didn't have the luxury of ignorance. Mills said many became "lay anthropologists," studying the culture and mindset of a white tribe that had frightening power over them to "determine their life and death on a whim."

Mills quotes the author James Baldwin:

"I have spent most of my life, after all, watching white people and outwitting them, so that I might survive."

Can you disagree with a person about race and not whitesplain?

Here's a philosophical question that Mills didn't explore: Can a white person disagree with a person of color about a racial issue and be right? Does skin color grant infallibility in all cases when a person of color says, "That's racist!"

Not necessarily, says Johnson.

She says people of color disagree all the time about what constitutes racism. So can white people if they display one important attitude during a debate over racism:

Humility.

"A lot of times people just want to be heard," she says.

Colin Kaepernick was the subject of a recent "whitesplaining" incident.

"It doesn't mean you have to go all out and say, 'You're right, I'm racist and I apologize,' and fall all over yourself apologizing," she adds. "But just for the sake of validating that person's experience, you can say how it's entirely possible for you do a thing that you didn't mean to be racist."

"Racism is not an argument about an idea," he told CNN. "It is an argument about experiences and emotions. So just because someone does not have racist intentions does not mean their actions do not have a racist impact."

Prescribing a liberal dose of humility can't work, though, if some white people aren't willing to listen.

When someone is determined not to see a person of color's experience, there is no cure for whitesplaining.

It just keeps spreading.
