As most Americans collectively remembered the tragedy of Sept. 11, 2001, a quarter-century after the terror attacks killed nearly 3,000 people, pockets of denialism have sprung up to tarnish their memories.

A recent study from the University of Wisconsin-Madison found that only a handful of states have statutes requiring or encouraging the terror attacks to be included in either curriculum or school wide activity like a moment of silence, according to Fox 11. 

The report found that only Arizona and Florida have standalone laws requiring 9/11 education, but that five states require a 9/11 observance and nearly two dozen more require some instruction on the topic – but that instruction varies widely among the states.

For example, Fairfax County in Virginia – a state that merely suggests teaching students about 9/11 – recently came under fire for refusing to link the terror attacks to “Islam or Muslims,” with half of the school’s guidance devoted to protecting Muslim students, Fox News reported. 

The six-page instructional guide, titled “25th Anniversary and Commemoration of 9/11,” advises teachers to create “safe spaces” for Muslim students while discussing the terror attacks.

"It does surprise and shock me that Fairfax, Virginia, is saying we will not use the words Islam or Muslim in relationship to the 9/11 attacks when that was literally in the shadow of the Pentagon, and they're saying no, we're not going to use those terms," House Permanent Select Committee on Intelligence Chairman Rick Crawford said Friday on Just the News, No Noise. 

"That is an absolute travesty, and I think you know you're spitting on the ground of 2,977 Americans who died that day. So, I don't really think that I will be giving much quarters to those folks who have that perspective."

The guide mentions military families only three times and first responders only once but has 30 references to Muslims and Islam in the context of protecting those students from bias.

As former chief of staff to the National Security Council, Fred Fleitz wrote at American Greatness, the truth about 9/11 must be taught.

“This was done by radical Islamist terrorists who hate modern civilization, hate modern society, hate freedom, democracy," Flietz said Friday on Just the News, No Noise.

"This was not just an attack against the United States. This was not an attack against American policy in the Middle East. If it was, why were there similar mass radical Islamist attacks in Brussels, in Berlin, in London, Madrid, in India, too, in Bali, Indonesia.

"This has nothing to do just with the United States. This is an effort by radical Islamists to try to move our world to a medieval state where women are subjugated and treated very brutally, where people have their hands chopped off. I mean, it is a worldview that makes no sense in modern society, and because they can't get it by convincing people, they're using violence."

Fleitz also pointed out the Texas Board of Education recently mandated that students in the state be taught that radical Islam was to blame for the 9/11 attacks.

"If we don't recognize who did this and why, we can't defend against it. We can't stop it from happening again," he said.

In his column, Fleitz pointed to 2023 remarks by Minnesota Democratic Rep. Ilhan Omar in which she appeared to minimize the attacks by saying, “Some people did something” and left-wing influencer Hasan Piker saying in 2019 that “America deserved 9/11.” 

In New Jersey, curriculum created with the pro-Muslim organization CAIR-NJ and “Teaching While Muslim” tells students that the attacks were committed because the U.S. supports Israel, supported the Persian Gulf War and because of the American military presence in the Middle East.

“This is not teaching history," Fleitz wrote. "It is a radical woke attempt to rewrite history and explain away murder."

Rep. Warren Davidson, R-Ohio, called Omar's 2023 remarks "about as passive as you could get," reminding the Just the News, No Noise, audience that for a brief period after the 9/11 attacks, the country was united.

"The country came together in a spirit of unity that I don't think I've experienced at that level any other time in my life," Davidson said. "Three days after, Congress voted almost unanimously to go to war against Al-Qaeda and their affiliates, and we were laser focused on that for a time, not long, but it was amazing."

It’s not just schools rewriting history or minimizing the terror attacks. 

In New York City, where two of the four terrorist-hijacked commercial jets on 9/11 struck the twin World Trade Center towers, socialist Mayor Zohran Mamdani signed an executive order designating September 11 as a day of commemoration and service, but ensured the ceremonial pen he used to sign the order would end up in the hands of an attorney who represented a terrorist convicted of charges related to the terror attacks. 

A resurfaced quote from a year earlier also showed Mamdani, who won election last year as a Democrat, claiming 9/11 was a day that sparked Islamophobia.

“It was this horrific day that was also for many New Yorkers the moment at which they were marked an ‘other,’” he told The New York Times.

On Friday, during a remembrance ceremony, Mamdani and Rep. Alexandrai Ocasio-Cortez, D-N.Y., appeared to be laughing while the names of those who died during the attacks were read.

"The fact that they put a guy like Mamdani in a position to lead that city is inexplicable to me," said Crawford, an Arkansas Republican. "I can't imagine. And there he sits with his partner in crime, AOC, laughing as families are reading the names of their dead, as if there's something funny taking place that we're not aware of.

"I mean, if you can't maintain some sort of solemn decorum on a day like today, then go back to your office and chortle with your friends. But don't do that in public."

Canada also caused outrage when its public broadcaster, the CBC, told staff not to refer to the 9/11 attacks as “terrorism.” Swift backlash caused the outlet to reverse its policy.

And anti-Semitic conspiracy theories about Israel’s involvement in the attacks continue. 

On Thursday, the Anti-Defamation League (ADL) published an article about the conspiracy theories still affecting the Jewish community 25 years after the attack.

“Significant global events, including terror attacks and wars, are inevitably claimed to be ‘false flag’ attacks carried out at the behest of Jews or Israel, with the 9/11 attacks treated as a foundational example of these claims,” the ADL wrote.

The theory is that Israel carried out 9/11 so that America would attack its enemies in the Middle East, which requires ignoring the evidence of who carried out the attacks and why.

Also being ignored in discussions about 9/11 is the fact that the perpetrators used the immigration system to enter the country and plan their attack. 

Rep. Chip Roy, R-Texas, suggested that securing the U.S. southern border and cleaning up illegal immigration is another form of national security.

"We should connect it to terrorism and security and safety, remembering that the entirety of the 9/11 hijackers were all visa overstays," Roy said on Just the News, No Noise. "They all overstayed their visa. So, if [the Department of Homeland Security] was doing its job, we wouldn't have ended up with the environment where you have overstays who sat here and then flew planes into the World Trade Center. So, don't tell me that dealing with immigration and enforcement isn't national security and doing what we need to do to keep our eye on the ball."
