Wow - someone had a bad time in elementary school. If they don't "comply" with what they're taught, they fail. So it's a big conspiracy against kids who don't believe pi is 3.14 or that the sky is blue? God forbid that people who never learn how to put 2+2 together or who won the Battle of the Bulge can be denied positions of power.
How would you rather they teach grade school?
Teacher: "The sky is blue, but go with what you feel, kids."
Kid: "I think the sky is green."
Teacher: "Go with that idea, Bobby. A+"
Now you tell me how that child is prepared for real life.
