Your position doesn't make sense. We know that testimony on atrocity propaganda is sometimes a complete fabrication:

So that is one of the things worth considering, but that hypothesis isn't a get-out-of-jail-free card and needs to be weighed against other factors like the variety of sources and people involved, their history and material interests, etc.

Yes, I am saying things need to be scrutinized instead of just taken at face value if they comport with our prejudices, I apologize if that takes the wind out of your sails, but blind faith won't lead you to good conclusions.
