Misknowledge!! I like that.
I have a nephew that keeps a radio on Rush all the time he is on.
He believes in Adam and Eve..real ancestors of us, but not of non-whites. Widen Earths orbit by only six miles, and we all die. (maybeso, if it is done in an instant!! LOL!)
He is my nephew, and my best friend. He knows what is good to eat, and is a pretty good mechanic. So Ignorant does not quite fit.
