My dear Think About It...purple barrels or orange microdot?
Unfortunately it sounds like you were on a bad acid trip. But then again weren't we all?
I began my study when I was 21, in 1979. By this time you only heard the , unexplained 1975 comment. A few times I heard about the great Bethel apostasy in passing. When I questioned the meaning of these random comments it was immediately pooh-poohed. I never experienced it first hand. I always had a sick feeling in my gut though, like "Hello McFly, is anybody home?" I wish I could have snapped out of it and woken the hell up.
Praise be to my god, THE MIGHTY INTERNET, may it save us all.
