I fully understand why people are starting to believe this, as such a belief system seems more parsimonious with all that we know today about what most of the Jewish people are doing to the Palestinians, and by how many lies and how much propaganda comes out of Israel. But I believe the holocaust did happen because there is too much data about it (ask your eldest relatives what they think and why). It is actually more parismonious than it seems. The abused becomes the abuser.
