"...assuming people are so dumb is patronising a whole generation into stupidity." I guess that is actually being done through the school systems.

As far as flat earth goes, I will stand up, with math, to any question. The entire generation of flat-earthers are so jaded by the lies that are given to us through corrupt governments that they are sucked into anything that is not mainstream. 500 years ago science was just starting to bubble into a froth and our knowledge was brimming with ideas, the walk away from the flat model punishable by the governments, since the heliocentric and flat earth were what all the failed science was based on, since the move into calculus, and the globe earth we have lost all the garbage science and replaced it with better science, In fact Kepler wrote the science of optics in a little over two weeks once the idea of spherical planets was accepted, and he was allowed to finish HIS invention, the telescope. While Galileo was credited with this, he was just a pawn in the game, Kepler took all of the data Tycho Brahe observed and created the, almost perfect, science of orbital motion and periods of the planetary motion.

Now I am in no way saying our current science is where it should be, in fact I believe we need to pay far more attention to magnetism than we do, but the reality is that, We are far more advanced than we were, when the flat earth was our basis. Flat earth changes our physical science and puts us backwards 500 years, and the entire system would need to be reconsidered. I do not think that needs to happen, in fact, in my opinion, we need to readjust the scientific system we have.

I can say without hesitation, we live on a spheroid and not a piece of paper. Without global spin, we would not have currents, well I guess I could go on an on but I'm sure you get the point.

You say you have no dog in this race, but maybe you should. Living without opinion on such a matter is, well, boring. Investigate and chose a point. Not believing in something is like not having any direction. In any direction, you are correct that the mindless approach they used was just as stupid as the flat earth idea.
