Logical fallacy. Not any evidence of flat earth provided, nor an argument for flat earth. The promulgation of incorrect information can be done just as easily as the promulgation of correct information. But just like the majority of flat earthers, you propose an argument that strokes the ego of people that they are 'intelligent' and have discovered something that 99% of the population have not discovered, and it makes them feel good that they can be so smart without having to do any science, math, or research themselves. They can just watch some YouTube videos and find out more than all of the scientists in the past 2000 years did!

It's a very alluring fallacy, for sure.

The reason it's becoming a 'thing' is because of a charasmatic leader giving good-sounding arguments and ego stroking to people unwilling or unable to do actual research themselves.

Case in point are the videos on YouTube about a flight from Asia making an Emergency landing in Alaska. The people promulgating these videos don't even use a globe to prove how the emergency landing on a globe would be perfectly natural.

Instead, they make a good sounding argument that most people are too dumb to see through, and certainly will not fact check themselves. But arguments like these are nonsense, ad hoc, and are incorrect at best and intentionally deceptive at worst.
