Today I came from talking to my 74 year old dad. HE lashed out about me not believing in the "faithful slave" because of all the changes. He said that he does not remember any:
Transplants : never heard about the change
Smoking: Never heard about it
Blood changes: a provision from Jehovah
1975 : the slave never said it - just the brothers
Generation change: Never happened / he can't remember
Then I quickly found the page here that shows the flip flop on Sodom and Gomorrah, he said it is all just new light and that things change.
I have no idea how they can all remember new light and to blame the flock but the can never remember the tom-foolery that is giving to them on a regular basis
