That is the reason Ignorance makes me mad. I can love anybody if they don't know any better or aren't capable of understanding something.
But it is hard to tolerate those who have an agenda (like being superior to others) and want to stay ignorant, refusing to even discuss things. They ignore the facts and hold on to their uninformed opinions and they don't want to be honestly educated about things.
You are right. THey are the root of suffering all around the world.
