I have got a friend who has a very warped sense of history. His knowledge stems from anime, manga and documentaries. He is unable to critically evaluate his sources given his very lack of knowledge.
He has no sense of perspective at all and is very selective in his interpretation. He often thinks that he knows but his lack of breath and depth dooms him to repeating soundbites from bad documentaries.
I hope in time to come, he can read more from proper sources, learn to think critically and evaluate his sources and from there, grow.
