you haven't accepted blood yet, so you have DONE anything wrong... technically. However, you have "promoted" your opion to your wife, and additionally you have rejected the direction (or at least questioned) of the F&DS.
I believe they will take this in 2 forms. 1 - keep your opinions to yourself and wait on Jehovah, and 2 - do you beleive the F&DS is the sole channel being used by Jehovah.
if you say you accept the F&DS, they will use this to attack your reason for questioning the blood issue in the first place. They will drag this out for a bit and then, since you "accepted" the F&DS as the channel, they will shift back to point 1, that is, keeping your mouth shut about your issues and waiting on Jah.
yes its BS, but many have done this BS dance to keep from being DF'd by plumbers and janitors.
