Interesting thread Daniel. If I'm right, you are are also a swiss.
I would also accept blood if my life would depend on it. This was acutally the first issue I deeply researched and that woke me up 2 years ago. I just stopped attending from one week to the other and almost never returned. It was hard for my wife, but she accepted it. I also stopped talking to the eldubs as I figured that they were just (in)questioning me and did not offer any real help for any question. So no point in talking to them if real questions are not allowed - I can read WTLib on my own.
I expect you to be dissacotiated by expressing other belives but it may depend on your eldubs. Let us know what happens.
Regards, Mark.
