So as to the wedding ring/birthday comparison....
Im trying to think why that is...could it be that the wedding ring serves the JW purpose of "hands off - they are married" whereas the birthday idea serves no JW ideology?
Its more cherry picking if so. The goal then should be to find a way to make the birthday celebration "work" within the JW construct.
Then it would become a conscience matter and finallly accepted.
Birthdays for all!
