It isn't compulsory for your family to behave badly just because some Elders do ..... especially if they don't agree with the decision and how it was made.
Tell them that if they don't want the stigma of associating with a DF then they better grab the Elders & CO by the scruff of their necks and call them out for every rule they broke.
Ask them to show you from the Bible where it says you should have to sit in the back row and talk to your shoes for a couple of years just so that they aren't required to behave like are souls?
Cheers
