I have no idea what you are all talking about but if you want to try and help someone who is OTD:
DO NOT try to make them religious
DO be someone they can trust and just talk to without needing to worry about religion becoming the central topic
and DO NOT ever (if your a sibling or something) tell your that kids parents about things you think they are doing wrong. (It will justt make them trust you and other people less and that kid will just learn to hide what they are doing better next time.)
You may not change anything now but in 5 years at least that kid will have a religious freind who they can trust .
If you think by getting freindly with them you will emulate them then dont avoid all contact with them. Try to limit it but DO NOT completly cut them out. (It will just make them hate religion. Trust me i know)
