You need to get the most trustworthy books you can and look at historical documents yourself (you might have to visit a library!). Scrutinize the credibility and bias of your sources and then draw conclusions. Fact: nobody you know personally has ever done this, and the people who have done this do not get published.
Oh yeah, and Hitler was not the opposite of the left. People have a tendency to try to view things as polar opposites or to view them as having a two-sided nature. This is false, and intentionally perpetuated by communists/socialists (no difference in my mind). They would have you believe that the political spectrum has Hitler and Stalin at opposite ends with our system in the middle somewhere. This is entirely false.
