Flat Earth Theory is practiced by Flat Earth Organization or Society where people who believe that the Earth is flat (Flat Earthers) diss existing theories and evidence and support their own theories to explains the true nature of Earth.
In order to actually believe that the Earth is flat in the modern day, you need to also believe that just about everything else is also fake, including every single observation made by astronomers, every photo of the Earth, and even gravity.
While "we have a video from space - of a rotating spherical earth", the people who believe that the earth is flat do not believe it. A look at Google search trends for "flat Earth" show interest surging since January 2016.

"What's odd is there are people who think that Earth is flat but recognize that the moon is round", Tyson says.
An example of a flat Earth proof is a study that was repeatedly conducted over a body of water stretching for an average of six miles. There is a famous experiment that proves flat earth theory called as "Bedford Level Experiments" that was conducted many years ago and has since been conducted a number of times to prove that the Earth is a flat surface and not a round surface. He noted that the other planets in our solar system are also spheres, explaining that it's due to the laws of physics, which favor spherical shapes whenever bodies are forming in space.
And then there's the much more straightforward argument that if you watch a ship sail off, you'll eventually see it disappear into the horizon, and it would only disappear from view if it's moving on a round surface. If it was flat as a pancake, it is unlikely that the ship would behave as such.More news: Real Madrid coach Zinedine Zidane reveals captain Sergio Ramos' embarrassing situation
If three deep wells are dug at three different positions, and the sun is overhead the well in the middle, it would be visible to the bottom.
This explains how sunlight from a sun propagates towards the Earth and illuminate things at a different angle.
In typical Tyson fashion, he introduces several pieces of evidence throughout history, be it from the time of the ancient Greeks or from far more recent research done by our fellows, adding, "That's okay, as long as you don't run NASA".More news: Man Utd midfielder Michael Carrick confirms retirement from football
The discussion featured in the video is based on a chapter included in Tyson's book Astrophysics for People in a Hurry.
Neil deGrasse Tyson blames the educational system in the USA for the perpetuation of the flat Earth theory because he doesn't think it teaches critical thinking skills.
