I can understand this must be awful. BUT if your daughter loves you, the very fact she is asked not to speak to you based on something you did when you were 14 should prove to her the religion is a load of s****
What message are you sending her by being reinstated?
Personally I've faded, but could be DFed, my children still attend, my son aged 12 said to me categorically that the day they told him he couldn't speak to me was the day he'd leave. This fills me with confidence that they will see the org for what it is.I never badmouth the organisation I just say to them both that I will love and support them whatever choices they make, and I point out that I wasn't that lucky, my parent would only support me if I made one choice. Therefore I had none.
I think hang tight for a few years. you know kids (especially girls) at that age are very into religion, wait til she discovers boys, friends, and wants to do her own thing, I think you'll find this is all a distant memory and she will never be baptised.
If you are reinstated you will have to keep a very low profile to avoid being DFed again.
Obviously all your decision, but I could never go back for any price.
