The poster is well aware of the reality of Soviet interdiction to perpetuate the hoax with their staff of 7 million, alongside their Polish counterparts with a staff in the millions also. These people had committed tremendous crimes at Katyn, Kurapaty and Vilnitsia; it was imperative to blame the enemy for their own misdeeds.
The mentioning of indoctrination is really the poster Nessie reflecting on his own meagre performance in this field of history.
Due to deliberate dismantling of evidence, under their control, along with an attempt to portray a fake story the Soviet account is slowly eroding apart, the rust is flaking away to show a new interior of what happened.
The poster is misguided in thinking that this is normal history with normal rules; most historical events do not have a staff of 7 million over many years trying to obfuscate the reality.
The evidence is there such as the correlation between Fritz Reinhardt, Reinhardt program, Customs officials at border camps correlating with AR camps, photos of Zollgrenzschutz at the border camps.
Take Belzec, people head to Belzec never to be seen again. The hoaxers scream they were murdered by gas, steam, electrocution and by train. We find out that there was a customs office at Belzec which means people simply crossed the border into the Ukraine.
