"ignorance is strength, since it gives the strong in mind, power over others niavity or ignorance"

Won't tackle the others because they belong in a different debate context, maybe political but not PC, I think.

Anyone who would use another's ingnorance against them, to harm them, to hurt them, those kinds of people to do not, in my opinion, posses "strength." Strength is a positve trait to me. When you use what ever talents or material wealth or power of position to harm others that is not strength. In my opinion, that is abuse.

Someone who has true strength, will try to teach those who are naive or uneducated. They will try to help others learn what they need to know or understand to help themselves. Using your strength for other than good is abuse.
