Is it? Because plenty of other hoax-based bullshit, like Flat Earth Conspiracy Theorists and those who believe that the Earth is only 6,000 years old continue on in their bubbles regardless of how much evidence is provided to the contrary.
Most people find that it's more complicated to work with, since it requires a vastly more complicated set of initial conditions. But if you find that it works for you it isn't actually wrong.
A good self-test is asking yourself how you know the Earth isn't flat. Don't do any research, just try to work it out from what you've already observed and think what makes you believe that conclusion.
But then perhaps over time, they somehow attracted people who genuinely are that stupid, and uncritically believe? That demographic is obviously going to be too stupid to critically assess any new evidence either.
or just the “obviously stupid” ones?
We are barely sentient shit slinging apes.
As a schoolkid, our physics teacher was a flat earther. He drove us kids mad arguing with him that the earth is spherical.
Canny bloke.
