Is there really a difference? I feel like if you don’t know something, that kind of makes you stupid, right? If you don’t know historical facts or mathematics—at least the harder stuff, like algebra or calculus—or if you don’t know about advanced political topics, then you’re kind of a stupid person, not just ‘ignorant.’
Ignorance is a clack of knowledge.
Stupidity is a choice to not learn.
Some one who is ignorant, can cure that by learning. Some one who is stupid never will.
