I'm too young to speak on flip-flops per say. I'm in my early thirties, and haven't paid much attention to serious doctrinal questions until the past couple years. Had it not been for this forum, "This Generation" wouldn't have even been a minor blip on my radar.
I have to say though, the more I research and the more messed up things I find in the WT's history, the position on transplants really stands out to me as spectacularly crazy. To compare it to cannibalism, is just beyond me. I find it hard to imagine that grown men actually collectively sat down together and let that hit the presses. You can't blame all of that on Freddy, or Knorr. The argument that organ transplants was equivalent to cannibalism had to have raised more than a few red flags right? To think that it got past several organizational barriers and then ended up in the very magazine that the WT is chiefly associated with speaks volumes about this supposedly being God's chosen organization. It speaks volumes on their so called "Noo Lite" when they finally reversed that position. It's mind boggling.
Another crazy thing was the articles in the past that stated blood transfusions caused individuals to retain the negative aspects of their donors. Such as if your blood transplant came from a criminal, then its highly possible you'll turn into a criminal. My memory might be mixed up, it was either blood transfusions or organ transplants on that one. At any rate, either way its crazy, considering they're now allowing blood fractions, and allowing organ transplants. Whether I eat piece of pepperoni and cheese off of a slice of pizza, or I eat the entire slice, people would still say I had my hand in the pizza box. Yet the WT doesn't see it that way. They would ask the question, what constitutes a slice of pizza? Buncha peculiar old white dudes with a token black dude up in Bethel man. By the way, another flip flop to consider would be that the very men that Samuel Herd idolized when he was young, believed that he would become white one day.
