One interesting commentator on youtube is “mropendialogue”.
You can go to his web site and see a variety of interesting contrarian videos mostly about issues relating to WWII. One of my favorite presentations in mropendialogue are the following dealing with the holocaust:
The video below by Germar Rudolf and the repression that he has suffered makes one think that Germany has made little progress in civil rights since the third Reich. The fact that people in Germany and other European countries are thrown into jail for years for expressing opinions or doing basic research is more appropriate to a classis dictatorship than a modern democracy. The whole reality is disgusting. The video is definitely worth a listen.
