The recent failed SpaceX Starship launch flushed out the "Flat Earth" retards in droves, making "FIRMAMENT" trend on Elon Musk's X.com. Is it a psyop targeting fuckwits? Yup. Check this graphic sowing the obvious #'d BOT ACCOUNTS. Each account tweeted random Flat Earth faggotry. INFORMATION WARFARE!

🧠 These people are stupid!
Flat earth is a roadblock put up by ds/kazahrians.
The reason so many follow the whole flat earth nonsense is because a LOT of the roads that led to that roadblock are very much valid and leads somewhere beyond that roadblock, the flat earth roadblock works by providing the psychological satisfaction of an 'answer' that removes the reason/motivation for continuing to dig.
So flat earth was created as a target for ridicule because they REALLY do not want people going further down the roads that introduced them to that roadblock, ridiculing and dismissing stuff because fLaT-EaRtH is what they want people to do.....
There is more there and dismissing it because of their roadblock is playing right into their hands.....
As to the firmament:

It is just one of the roads that leads to the flat-earth roadblock, there is more to find....
How in the world does FE give cause to stop digging any more than "the CIA assassinated JFK" or "vaccines cause autism"?
They don't have to 100% stop 100% of the people, just enough to make those that continue digging dismissible, people are hardwired to lie to themselves and being 'right' is a powerful feeling(pretty much all socials on every topic proves this....)
It's all about the numbers and the traction, people are barely awake enough to be willing to sorta start thinking there might be something to the 2 other examples you mentioned........
It's a variation of the whole 'you don't have to fool all of the people all of the time, just enough of the people enough of the time' thing, same concept applies to rather a lot unfortunately...
