What's funny is that many black people have adopted the word "ignorant" as some sort of debate end all or protective cloak from facts they don't want to hear. When you raise those facts or draw logical conclusions based on those facts it's because, to them, "You so ignorant!" or "Dat's ignorant!"
In reality, you're the one with the facts and they're ignorant of those facts, but that doesn't stop them from throwing out that word.
