Everyone like the smell of their own brand. The point is to not make the mistake of thinking that you liking your brand has to also go for everybody else. Saying that you have the facts without an interpretation is the equivalent of making that statement.
If you don't have solid numbers from before, how can you be certain of the difference afterwards?
And that doesn't detract from the fact that the events have been used 70 years later politically to benefit a particular group who has a motivation to make sure the numbers remain as disasterous as possible.
Yes, well unfortunately for the denialist narrative, actual numbers based on camp records and other records from Nazi archives have provided the figures reported. Primary evidence, available for inspection.
I have seen many of these records first hand at Auschwitz, Topography of terror museum, SS museum in Cologne, Nazi museum in Dusseldorf and Budapest.
Alamanc numbers are merely somewhat corroborating evidence.
