I'm getting the feeling I should not meet with them but I want to know why.
Because elders can be sly buzzards. Their meeting with you could easily be the first step to a Judicial Hearing. They are good at asking loaded questions and could easily trap you into saying something you didn't intend.
As pointed out, you have already mentioned to your husband that you don't accept the blood policy, so it's going to be hard to reverse yourself on that. You will either have to lie through your teeth and say things you don't believe to satisfy them, or tell the truth and face consequences.
All of this is done in the name of love and helping someone spiritually. If you are marked or DF'd in the end they will tell themselves they have done the loving thing and you will suffer for it.
Best advice, as given above, is don't get started with them.
