The net of a thousand lies
The most surprising thing about the rebirth of flat Earthers in the 21st century is just how widespread the evidence against them is. You can understand how, centuries ago, people who’d never gained a high-enough vantage point from which to see the Earth’s curvature might come to the commonsense belief that the flat-seeming Earth was, indeed, flat.
But today, when elementary schools routinely dangle GoPro cameras from balloons and loft them high enough to photograph the Earth’s curve — to say nothing of the unexceptional sight of the curved Earth from an airplane window — it takes a heroic effort to maintain the belief that the world is flat.
Likewise for white nationalism and eugenics: In an age where you can become a computational genomics datapoint by swabbing your cheek and mailing it to a gene-sequencing company along with a modest sum of money, “race science” has never been easier to refute.
