from the UK!Sorry, I have little practical experience with which to address your OP. I feel that, knowing religion indoctrination to be harmful to children, I'd be looking for ways to reduce the religious influence from other parts of the family. I know I do for my son but it's easy for me as someone who's free to announce their irreligiosity. Teaching them to think critically is probably the best armour; that can be done without having to out yourself to sensitive family members.
