Having said that, I think the practice of JW elders on the ground has softened markedly in recent decades. I know from experience there was a very light touch from elders around “assistance” to avoid blood, and also a degree of respect for privacy. I don’t know if that’s a result of direct instructions or just the approach of local elders, but I suspect that, as with many things in JW culture, the attitude of ordinary JW has become less hardline, or more apathetic to the blood teaching, to put it in more negative terms. The days of kidnapping children from hospitals and spying on fellow believers and leaking medical documents by JW hospital workers are all long gone.
The GB may never come out and reverse the blood ban but they do seem to be loosening the grip on enforcement. People who take blood seem more likely to be viewed as having made a mistake due to weakness, and need shepherding, rather than automatically DAed. This is my impression anyway, I’d be interested to know if others have observed this. The situation where they would still take a tough stance is probably where somebody takes blood and makes it known to others in the congregation they think they are doing the right thing. In that case they’d probably get DAed or DFed more for apostasy than for taking blood as such.
