i think the topis is about younger children and not 15 - 16 year olds who can clearly understand that this kind of behaviour is wrong.
I know of a girl aged between 5 and 6 who was molested by her own mamoon, why wouldn’t I fear for my kids then.
I trust my brother and my brother in laws, my sisters and my parents but I will definitely be careful and not leave the kids ever completely alone with rest of the uncles and aunties.
