It's been pretty well settled that Representative Marjorie Taylor Greene is not a healthy person. There's not a conspiracy theory that she hasn't liked with a major affection for Qanon nuttery.
One of my personal favorites is her espousing and then expanding on the Qanon conspiracy theory that the deadly 2018 California fires, especially the Camp Fire, was caused by space lasers:
Conspiracy theorists have pushed other explanations for the Camp Fire, especially on social media. One theory, which has been promoted by QAnon followers, falsely posits that a nefarious entity used laser beams or a similar instrument to start the fire for financial profit or to clear space for California’s high-speed rail system.
Rep. Greene is a proponent of the Camp Fire laser beam conspiracy theory. She wrote a November 17, 2018, Facebook post -- which is no longer available online -- in which she said that she was speculating “because there are too many coincidences to ignore” regarding the fire, including that then-California Gov. Jerry Brown (D) wanted to build the high-speed rail project and “oddly there are all these people who have said they saw what looked like lasers or blue beams of light causing the fires.” She also speculated that a vice chairman at “Rothschild Inc, international investment banking firm” was somehow involved, and suggested the fire was caused by a beam from “space solar generators.”
Greene added: “If they are beaming the suns energy back to Earth, I’m sure they wouldn’t ever miss a transmitter receiving station right??!! I mean mistakes are never made when anything new is invented. What would that look like anyway? A laser beam or light beam coming down to Earth I guess. Could that cause a fire? Hmmm, I don’t know. I hope not! That wouldn’t look so good for PG&E, Rothschild Inc, Solaren or Jerry Brown who sure does seem fond of PG&E.”
By this time, I was really hoping to see that the culprit was a race of lizard people that came to conquer the Earth. But nope, not this time. Instead she blamed Jews:
The Rothschild family has featured heavily in anti-Semitic conspiracy theories since at least the 19th century. Anti-Semites have generally updated the theory by replacing the Rothschilds with George Soros, a more contemporary and plausible-seeming mastermind for a global conspiracy to spread left-wing ideology. Greene’s version has instead updated the theory by giving the Rothschilds possession of a secret, powerful space laser.
Now, you might wonder why, if an international cabal of Jewish bankers wanted to finance a rail project, they would go about it by using their space lasers to set a catastrophic blaze. Aren’t there easier ways to get your rail stations approved by the state legislature? If you can pull off a massive conspiracy like that and keep it quiet, and you have a space laser you can use to immolate basically any target on Earth, there have to be more direct profit-making opportunities than burning down trees in order to arbitrage the land value for a public-transit contract.
On the bright side for her, after she gets expelled from Congress, she could always apply to be a Space Cadet in the Space Force. That seems more like her speed anyway.
