Okay, I've read everything on this thread. Here's my view on the whole thing...
This is NOT going to have a huge effect in courts when it comes to the actual blood issue. For JWs, the main reason to avoid blood transfusions is because Jehovah apparently says it's bad in the bible. The medical aspect, although falsely presented only strengthens the R&F's standpoint on the issue.
HOWEVER, the blood brochure DOES get placed out in FS (at least I think it does). They use this to convince non-JWs that the whole no blood thing is a good idea. However, it again reverts back to it being a biblical issue.
BUT, where this essay could come in useful, is it's a publication that shows that the WTS makes shit up. Most non-JWs don't really know nothing about the JW religion, so they don't really care how they spin this doctrine. However, they do care if they're being decieved. That's how this article could be used in other ways, ways that the WTS lies for its own benefit. The whole "Theocratic Warfare" strategy the WT uses will back up this article. This is where we can hit them.
Going through the courts is an expensive and risky way to use this information. Attacking the WTS's benefits which they lied to get, will be much more effective, less expensive, and less risky.
How this article will benefit people immediately is getting people (like my friend) who left the JWs but still agree with their stance on blood, to change their mind. That's it.
The news isn't big. It's not even new information. It's just a tool. A tool that can be beneficial, or possibly used for bigger things. However, don't take it at face value (blood issue). Take it for it's deep value, which is lying.
