“One kind of ignorance is willful stupidity; worse than simple stupidity, it is a callow indifference to facts or logic. It shows itself as a stubborn devotion to uninformed opinions, ignoring (same root) contrary ideas, opinions, or data. The ignorant are unaware, unenlightened, uninformed, and surprisingly often occupy elected offices. We can all agree that none of this is good”.
