Ask them how likely was it that germany knew the post war Demarcation lines so that they only built death camps where bolsheviks propaganda departments existed rather than allied news reels? Or was it more likely that all camps were work camps that suffered immensely from overcrowding and disease but even worse. Mass starvation at the end along with all of occupied Europe because the allies bombed food transportation? Which BTW we know they did. Bombed food supplies. Starving prisoners and Germans. Nah no correlation.
