After my DF'ing I decided no-one was going to put me down just because I no longer held the same religious convictions as others did. When my parents remarked how difficult the situation was, I told them that it was their rules that were causing a problem, not mine.
Eventually I did get some small degree of satisfaction when one witness told me that I needed reminding that it was they who were shunning me, not me shunning them. I just walked away, feeling much stronger.
