imo, the easiest way to learn is to look up videos or works from the likes of frederick toben and david irving. irving is better i think cuz he at one time was Europe's most sought after historian and very famous until he looked into ww2 lol. now he's considered a nazi with zero credibility. and plus his court battle was pretty epic they even made a movie about it, of course it was the evil nazi sympathizer vs thos poor jews....
