[1] She came to further prominence in 2010 for leading the campaign against the proposed Park51 Islamic community center, which Geller called the "Ground Zero Mega Mosque.

"[7][8] She is the president of Stop Islamization of America (also known as the American Freedom Defense Initiative), an anti-Muslim group which she co-founded with Robert Spencer.

[9][10] The British government barred Geller's entry into the UK in 2013, citing her anti-Muslim activism, and saying her presence would “not be conducive to the public good.” She has been targeted in an assassination attack by Islamic fundamentalists.

[15] In a Village Voice interview, Geller indicated that she had only become political since the 9/11 attacks,[16] after which she began reading authors on Islam such as Bat Ye'or and Ibn Warraq, saying she "spent years studying the matter before I started blogging.

[1][17] She has referred to her blog as “my living room and kitchen—a place where she can kick back and yell, like some people shout at their TV,” in contrast to her books and published articles, which are “more studied and more measured.”[2] The blog gained attention in 2006, when Geller reprinted the controversial cartoons of Muhammad that were originally published in the Danish Jyllands-Posten newspaper.

[1] In 2007, her campaign against an Arabic language public school in Brooklyn was said to have played "an important role" in the resignation of its principal, Debbie Almontaser.

[20][21] In 2010, Geller co-founded the American Freedom Defense Initiative organization (AFDI), also known as Stop Islamization of America, with Robert Spencer, an anti-Muslim activist.

[26] At the 2010 Conservative Political Action Conference (CPAC), Geller criticized the Pentagon's report on the 2009 Fort Hood shooting for failing to talk about the religious motivations behind the attack.

[24] Israeli columnist Caroline Glick disputed the assertions by White and Davidson, and argued that Geller opposed jihadists, not all Muslims.

[38] In November 2018, the website falsely claimed that former National Security Advisor Michael Flynn had been cleared of criminal wrong-doing in the Russia probe.

"[7][8] Geller claimed that Park51 is viewed by Muslims as a "triumphal" monument built on "conquered land,"[41] and asserted: “I'm not leading the charge against the Islamic center near Ground Zero.

"[45] According to Stephanie Wright in Fear of Muslims?, Geller's language in opposing the mosque was repeated by mainstream politicians, such as Sarah Palin and Newt Gingrich.

[2][46][14][18] Andrew C. McCarthy, writing in the conservative magazine National Review, criticized the CAIR spokesperson's remarks on the matter, citing his remark: “I wouldn’t want to create the impression that I wouldn’t like the government of the United States to be Islamic.”[47] According to Cord Jefferson in the American Prospect, “the media often craves controversy over substance,” and paid "disproportionate attention" to the Park51 story, thus furnishing “a small-time political blogger with an obsession” an opportunity “to hijack the news cycle for months.”[48] Stop Islamization of America has sponsored ads which carried instigative messages, such as "Fatwa on Your Head?"

[59][60] Some Muslims argued that Geller's use of the word jihad is identical to Islamic extremists', and too common in general American usage.

[71][72][73] In 2015, Geller announced that she would run ads on public transit systems accusing donors to the New Israel Fund of being supporters of the anti-Israel BDS movement, although a spokesperson from NIF said the charge is false.

[75][76] The same day, shots were fired outside the event in Garland, resulting in the death of two suspected shooters by the police, and the injury of one security guard.

[78][79][80] On June 2, 2015, a 26-year-old Muslim man, identified as Rahim Nicholas, was shot and killed by police officers in Boston, after he waved a military knife at them and charged at them with it.

Reported to have been radicalized by the militant Islamist group ISIS, Rahim was plotting to travel out of the state to assassinate Geller.

[110] In 2018, she falsely claimed that the Parkland shooter “was immersed in Islamic and leftwing hate.”[111] Geller frequently characterizes incidents involving Muslims as part of a "jihad.

"[112] In 2011, she warned of “Vehicular Jihad in Arizona,” after reports of a man named Ajaz Rahaman had crashed into a supermarket; it was later shown that he had suffered a heart attack.

[112] She also claimed "vehicular jihad" when an Egyptian immigrant drove a car onto a curb, hurting pedestrians; she omitted that the police determined he had fallen asleep at the wheel.

[112] Geller has mischaracterized a variety of different events as being a part of jihad, including: an incident that involved a mentally ill, teenaged Bosnian shooter in Salt Lake City; as well as assaults of Walmart staff and customers by meth addicts.

[112] In 2011, she removed posts from her website as part of the settlement of a defamation lawsuit; she had accused a Columbus, Ohio attorney of ties to Hamas.

[121] Political activist Charles Jacobs says that Geller takes aim at "radical Islam," comes to the defense of victims of honor killings, and deals with Islamist antisemitism—which the ADL and SPLC fail to address.

[122][123][124] Breivik, who was responsible for the 2011 Norway attacks, featured her writing in twelve sections of his manifesto, referred to her as a "decent human being," and noted that he had followed Geller's blog "for the better part of a year.

"[125] As the media began to report on her influence on the attacks, she removed statements from her blog that could have been considered incriminating, including part of an email that she posted in June 2007 describing a stockpile and cache of weapons, ammunition, and equipment being amassed by an Atlas Shrugs reader in Norway.

Geller wrote on her blog that "any assertion" that she or other anti-jihad writers bore any responsibility for Breivik's actions was "ridiculous," and that “If anyone incited him to violence, it was Islamic supremacists.””[122][126] She later described the location of the attack, a youth camp on Utoya Island, as "an 'anti-Semitic indoctrination center' where children with a 'clearly pro-Islamic agenda' play war games,"[125] citing as evidence a picture of the attendees of the camp claiming they "are more Middle Eastern or mixed than pure Norwegian".

"[30] Cited as evidence for the ban were statements categorizing Al-Qaeda as "a manifestation of devout Islam," and stating that jihad requires Jews as an enemy.

The nation that gave the world the Magna Carta is dead.” Hope not Hate, which led a campaign to ban her, applauded the decision, stating: “There is a line in the sand between freedom of speech and the right to use hate speech.”[30] In economics, Geller favors "right-wing," "small government" fiscal policies of cutting taxes and reducing budgets.

The four of them are social media influencers, running the Girl With No Job account on Instagram, and a Facebook Live/YouTube show called The Morning Toast.
