The problem is he's a racist crank with no expertise in viruses and a long history of writing nonsense.
His recent output on ResearchGate (which he was repeatedly warned about before the ban) includes articles claiming "vaccines are inherently dangerous" and that the surge in deaths last spring wasn't caused by covid but was "mass homicide by government response".
Before covid he was also a climate change denier.
A 2007 article claimed global warming was a "useful myth" that "deflects attention away from real world issues" such as "power-driven financiers, corporations and their cartels backed by military might".
This seems to be a common thread. As a physics professor in 2005 he turned an environmental studies class into a workshop on "what the high priests of science have been talking about and how science is being used". Without telling university officials.
One series of posts, in which he accused a law professor of acting like the university president's "house negro" and trying to discredit reports of systemic racism, later resulted in him being sued for libel.
He walked out of the trial (in which he was representing himself) after accusing the judge of being biased and running a "kangaroo court", and compared it to a Stalinist show trial.
When he was eventually fired by the university in 2009, accused of inflating grades after giving all 23 students on one course an A+, he blamed "the military industrial complex and the Israel lobby" for his misfortune.
This seems to have escalated into a full-on antisemitic rant, in which he apparently accused the "Israel lobby" of being "chief-whip for the US military economic finance empire" and providing "direct and forceful control of politicians and intellectuals".
A racist conspiracy theorist who believes Israel and its supporters in the US are secretly running the world, supported by the mainstream media and pop culture.
Maybe, as with Michael Yeadon's Islamaphobia, covid sceptics will turn a blind eye to Rancourt's antisemitism. Because he supports their beliefs on masks, lockdowns and vaccines (despite a lack of expertise in the field).
But don't let them forget they associate with racists.
In case anyone thinks this was an isolated incident, here he is again in 2014, tweeting about a blog post he wrote which says the Israel lobby "serves to align and discipline all the politicians" and uses the holocaust to "levy compliance".
His covid writings are equally crazy. Here he is way back in March 2020, suggesting covid-19 might be a biological weapon designed to kill Iranians, seeded in China by US soldiers, and that "media hysteria" about the virus was coordinated by the CIA.
🧵 Kate Shemirani's daughter sadly died last year, after refusing chemotherapy for her cancer, in favour of the kind of extreme quackery promoted by her mum.
Refusing to take responsibility, Kate accused the NHS of homicide and subjecting her daughter to medical experimentation.
Kate Shemirani and her ex-husband issued a statement after their daughter's death, wildly claiming that it was part of "a systemic pattern of state-sponsored medical homicide and institutional cover-up" by the NHS, and suggesting that she was part of an "unregulated drug trial".
Inevitably, Kate Shemirani and her allies are using the tragedy to raise money, claiming "they have taken her daughter". Their target is up to £100,000 to challenge the outcome of an inquest that hasn't even happened yet. So far they've only raised £2,455 from gullible followers.
Dilbert creator Scott Adams has sadly got prostate cancer. After going down a rabbit hole during the pandemic though, he turned to Canadian quack William Makis who (as always) recommended ivermectin and fenbendazole. Which did not work. Now they're in an unseemly row over it. 🧵
Ivermectin pusher William Makis responded to Scott Adams' post by claiming he didn't follow his "protocol" (which Adams denies), his cancer was "probably" caused by covid vaccines, and that he "didn't discount the possibility" that Adams was part of a plot to discredit him. 😬
Unsurprisingly Scott Adams is giving short shrift to Makis and other quacks and their followers, who are trying to blame his cancer on covid vaccines or encourage him to try anti-parasitics, vitamins, fasting, diets and other dodgy "cures" for his cancer.
This week sees the second "ARC Forum" in London, a right wing talking shop with overtones of Islamophobia, transphobia and climate change denial, funded by Paul Marshall and Legatum, who are also behind GB News.
Unsurprisingly there are a lot of familiar faces there... 🧵
Alan Miller from anti-lockdown turned anti-everything group Together is on a panel.
He was interviewed at ARC Forum by right wing channel Newsmax Australia, and was apparently "shocked to learn" that, according to them, Australia has no free speech and supports trans people. 🤷♂️
Toby Young founded Daily Sceptic, which like Together started out as anti-lockdown but then branched out into culture war outrage farming and omni-contrarianism.
It's still edited by a member of anti-vax misinformation group HART, who laundered their work through the site.
Struggling to get papers published? Why not start your own scientific journal? 🤷♂️ That's what the Great Barrington Declaration's authors have done.
Martin Kulldorff is editor-in-chief, and Jay Bhattacharya and Sunetra Gupta are on the editorial board. But wait, there's more. 🧵
The editorial board of the GBD's journal also includes their Collateral Global colleagues David Livermore (ex-HART), Carl Heneghan and Tom Jefferson (whose recent work includes dumpster diving "studies" misrepresenting responses to FOI requests from random members of the public).
Other familiar names include Scott Atlas (former Trump advisor, and co-founder with Kulldorff and Bhattacharya of the "Academy for Science and Freedom"), John Ioannidis (who, like Gupta, underestimated covid's fatality rate) and Marty Makary (Trump's nominee to head the FDA).
BREAKING: None of this is true.
The father was 18 at the time of the Rwandan genocide, and living in Uganda.
He's also a Tutsi - the victims of the genocide, not its perpetrators.
And Keir Starmer didn't represent him.
Needless to say, former Brexit Party MEP turned conspiracy theorist Jim Ferguson gives absolutely no evidence to support these claims, which seem to be based on social media rumours that have been circulating for months.
Conspiracy X's meltdown over Trump backing mRNA cancer vaccines is a thing of beauty. 😆
🧵
Apparently the mRNA cancer vaccines are "all part of the depopulation agenda".
Conspiracy X went from "Make America Healthy Again" to "oh my God, Trump's trying to kill us all" so fast they'll get whiplash. 😆
And if you thought "the depopulation agenda" was wild, how about mRNA cancer vaccines as a CIA assassination tool to off people chosen for termination by AI, or to "shut off people's connection to God"? 🤯
