As I commented on your article, growing up I learned of the Nazis using Jewish bodies to manufacture soap & lampshades. Turns out it didn't happen. There are reasons why many, including some survivors, believe it to be true. No one is lying, & no one is belittling the experience of others or trying to deny the Holocaust.
Getting history right is important. It's not disrespectful to question whether or not some of the more outrageous claims of atrocity actually happened.
