White supremacy is “a virus” that has been part of the American “subconscious” for years, according to Rep. Alexandria Ocasio-Cortez — and “clearly, our nation has not been inoculated,” she blasted Wednesday.

“It never went away,” said the Democratic congresswoman in a multi-tweet tirade.

“It was just dormant.”

Ocasio-Cortez, 29, had called out white supremacists earlier this week at a vigil for the mass shooting victims in El Paso, Texas, and Dayton, Ohio.

She also ripped into President Trump during the event, saying: “I don’t want to hear the question, ‘Is this president racist?’ anymore.”

“He is,” Ocasio-Cortez charged. “When we allude to people as an invasion, as an infestation, we are directly pulling from the language of white supremacy.”

The New York lawmaker has been urging Americans to “come back” from the “the grips of hatred and white supremacy” that — according to her — stem from the Trump presidency.

“White supremacy is like a virus,” she tweeted Wednesday night.

“Supremacists are those who have been completely overcome by the disease, but supremacy – the virus – exists on a larger scale beyond just the infected,” Ocasio-Cortez said. “White supremacy is often subconscious. & Clearly, our nation has not been inoculated. WS is our nation’s original sin; the driving logic of slavery, of Native genocide, of Jim Crow, of segregation, of mass incarceration, of ‘Send Her Back.'”

Continuing her rant, the freshman legislator said: “Healing ourselves of white supremacy will be hard. It will be hard because it requires us to confront *ourselves.* We wish it was as simple as denouncing a white hood, a burnt cross, vile language. But we need to address where supremacy *begins,* not just where it ends…Perhaps more than the obvious last steps of the supremacist, we must examine the nuance of their first steps. That is a painful inquiry, bc for many, we may see familiarity in those first steps. And that familiarity is very difficult to see + admit. We’d rather not talk about it…Recognizing white supremacy in ourselves – our institutions, our subconscious, our own past remarks or acts (no matter how consciously unintentional), is what makes the healing work ahead challenging. But it is not impossible, and confronting it is the only way to move forward.”

Ocasio-Cortez insisted that there “is a difference between white supremacists & white supremacy.”

“What this moment is asking of us is to discuss *white supremacy and racism* as much – or possibly more than – *white supremacists and racists,*,” she said. “When we do that, I believe we will start to make progress. But it is incredibly important that we recognize that perfectly normal, good people are capable of aiding racism & white supremacy. Recognizing that is not about pillorying people. It’s about learning to recognize *the virus* & end an oppressive system designed to hurt us *all.*”

Authorities believe the man behind the El Paso shooting, which left over 20 people dead and dozens more injured, was a supporter of white supremacy. He allegedly authored a racist, anti-immigrant manifesto — which referred to the mosque massacres in New Zealand earlier this year as part of his inspiration.

“In general, I support the Christchurch shooter and his manifesto,” wrote El Paso suspect Patrick Crusius. “This attack is a response to the Hispanic invasion of Texas.”
