What is now a pop culture meme aside, a real autist would know that our ocean trenches and mountains constitute a greater deformation of the Earth than the incredibly tiny oblation. The radius to the poles is only about twenty kilometres shorter than the radius to the equator.
You can't call the Earth an oblate spheroid without conceding that it's not a spheroid at all. The worst kind of pedantry is the pedantry that turns out to be wrong.
