Contrary to the Original poster, the blood thing always seemed right. If eating meat with little blood was wrong, then it would not have been given as a law back then, but it was. So the law applies to injesting whole blood, which means also transfusions.
Something that has always seemed not right is that we are to follow Christ's example in going door to door with the message. Or follow anything that the 1st century Christians did. They did what they did because that is the only thing they could have done. Why are we to follow their low tech ways?
The reporting of field service time and placements as if it is punching the clock or that it means something.
As to the destroying of all non-jws at armageddon: That didn't bother me because, being one, it wouldn't affect me.
I found it hard to accept that God allows hardships on people when he has the power to stop it when he is the God of love, but yet humans do things to stop evil with their limited powers. I never liked this defending of God no matter what.
