Yeah, JW farmers are not allowed to use blood-based crop fertilizers, because that would be disrespectful and too commercial. Yet the fertilizer would actually be poored out on the ground.
But accepting all kinds of commercially produced blood fractions and blood-based medicine is ok. Making your living working for SABM, writing procedures on when to administer blood is ok too.
Geez how could I ever have believed all these inconsistent rules...
