[24] In 2019, when making such denials to a journalist from The Times of London, Southern "end[ed] their conversation by predicting a race war.

[29] She was interviewed by the London Times in 2019: "When we speak, Southern flatly denies being racist or even far right, then ends our conversation by predicting a race war and quoting Enoch Powell.

[31] In December 2016, Southern self-published a short book Barbarians: How Baby Boomers, Immigrants, and Islam Screwed My Generation.

[30][32] In the book, she wrote: "As far as I'm concerned, Hitler was just a SJW who happened to get freaky amounts of power and actually implement his #KillAllJews (the predecessor to #KillAllMen) worldview".

[58] In May 2017, Southern, along with Martin Sellner and Brittany Pettibone,[59] took part in an attempt organized by the Identitarian group Génération identitaire to block the passage of an NGO ship, the Aquarius (co-owned by SOS Mediterranée and by Doctors without Borders), which was leaving Sicily for a search-and-rescue mission for ship-wrecked refugees and migrants off the shores of Northern Africa in the Mediterranean Sea.

[60][7] Claiming that the goal of the activists "was to stop an empty boat from going down to Libya and filling up with illegal migrants", Southern was briefly detained by the Italian Coast Guard.

NGO ships often rescue migrants and refugees, who disembark from Libyan shores on unsafe makeshift rafts, and bring them to Sicily.

[41] Southern has spoken in opposition to feminism[67] and has said that women are "not psychologically developed to hold leadership positions",[52] and "not going to be as great being CEOs".

[68] In June 2015, Southern reported on the Vancouver SlutWalk, a protest march of sexual assault survivors, for The Rebel Media.

Together with Tara McCarthy and Brittany Pettibone, she advocated for women to have fewer sexual partners, saying that the left holds "a cultural Marxist agenda that wants to destroy the family.

A multi-part interview of Dugin, conducted by Southern and Brittany Pettibone, was published on YouTube under the title "From Russia With Love".

[27] In February 2018, Southern, along with Pettibone and Caolan Robertson, distributed flyers in the English town of Luton describing Allah as "gay", as part of a social experiment video.

[81][82][83][84][85] Tucker Carlson of Fox News, describing Southern and the others as reporters, invited Katie Hopkins onto his programme to defend them against supposed political correctness responsible for their non-admission.

[97] In July 2018, Southern applied for a travel visa to visit New Zealand for a speaking tour with Canadian podcaster and YouTuber Stefan Molyneux.

[108] Tāmaki Anti Fascist Action spokesperson Sina Brown-Davis said her group feared "dehumanising depictions of indigenous people" in New Zealand.

[110] Green Party co-leader Marama Davidson added, "Aotearoa does not stand for your messages of racism, hatred and especially white supremacy".

[21] On 19 June 2020, Southern announced in a YouTube video her return and new plans, expressing some remorse for her previous hardline stances.

[22] Daniel Lombroso, in his article for The Atlantic, was skeptical of her change, stating: "She kept telling me she had grown more 'compassionate,' but whenever I asked her pointedly if she regretted her past work, I got obfuscation and tactical apologies.
