One of the tactics of communists is to destabilize a country by ripping out all the foundations of the society. History, morality, traditions all must be marginialized and eliminated as much as possible.
Here comes flat earth, to contribute to that. They love to come up with scientific-sounding explanations why the earth is a flat disk, and ignore basic physics. They toss around a lot of complex sounding explanations while ignoring observable facts and invent their own science. It's all done in an effort to destabilize the country, just like all the sexual madness that's being pushed.
Globe earth has been around (and accepted as the current science) for a relatively short period of recorded history. It is plausible that this is part of the communist tactic to destabilize a country (and the entire earth population). Gallup poll conducted in 2019 found 40 percent of US adults believe the earth is less than 10,000 years old and humans were created in their present form. Just some food for thought. Oh and our government space agency was founded by a secret society and the masons just happened to be the ones landing on the moon. Indoctrination starts when one exits the womb.
