greendawn,
:Did Franz have an obsessive irrational fear of blood and concocted the whole dogma out of this?
It wasn't Franz who originally promoted this idea. It was that crackpot wacko Clayton J. Woodworth. He went to prison with Rutherford in 1918 and he was the magaging editor of the Golden Age. He was the one responsible for all the rants against medical doctors, vaccinations and surgeries. He promoted that piece of junk Radio Biola in the Golden Age, and recommended what direction your head should face when you sleep. It was Franz who instituted the blood ban, but it was Woodworth who started things in motion for it.
