The Truth about the Nazi Gas chambers (Video banned on Youtube!)

Youtube removed this video along with another stating this about the video "Content glorifying or inciting violence against another person or group of people is not allowed on YouTube. We also don't allow any content that encourages hatred of another person or group of people based on their membership in a protected group. We review educational, documentary, artistic, and scientific content on a case-by-case basis."
After you watch this, do you feel that this is true or is youtube just trying to hide the truth?
