Thanks, TD. Good background info.
I just hate, hate, this wording that the WT uses:
"...and so we leave it up to the conscience of the individual ..."
What that really means is that the ordinary JW, who is striving so hard to be a "true believer". and desperately wants the paradise promise instead of the horrible Armageddon curse, will follow "the divine law" to the letter.
That is what my memories are like growing up in the dreaded bloody 60s - no blood of any kind, even if it was just a suspicion of a tiny drop. Mom was so careful making eggs - she would painstakingly remove any hint of blood from the raw eggs and would discard any that had obvious blood spots. Wieners and bologna was strictly forbidden - unless it was a specific Kosher brand (expensive, so we didn't buy them often) - because of the threat of blood that might have been included in the processing. I hated school picnics because all the other kids had a wiener roast. I had to take cheese sandwiches.
Oh, I could go on and on about how that awful blood brochure that was put out in 1961 affected my life. In so so many ways.
