I removed my blood card from my wallet shortly after I quit attending for good. Right after the release of the Silver Sword in 2013.
On closer inspection, my blood card had not been updated since 1999.

Let's say for the sake of argument that JWs have it right on blood.
How is sinning, by taking blood, different than any other sin?
If someone is about to commit fornication, should they intervene by committing suicide? No, they shouldn't.

My opinion says this:
JWs in private accept blood as needed.
It's the ones that feel compelled to share their medical history with nosy, gossiping JWs, "well meaning" family and or elders that get DF'd or tormented.
The obvious zealots suffer the worst, as it leaves them with loss of life under the pretense that they are pleasing Jehovah under the direction of the "current light of truth", that is -of course, subject to change without notice...
Bloodguilty. Watchtower is bloodguilty.
