Yep, the hall we used to go to had a big clean-up one day, and about 4 large boxes of society books were to be "thrown on the tip"
I protested and said "we were always told to "cherish our rich spiritual heritage", so we should keep these!
I was told by several elders that "we only need to keep the current 10 years worth of material"
Now, if that isn't re-writing history, and removing all awkward past material, then nothing is...
