Well said, and I strongly agree. Assuming all adults are dangerous to children and thus adults and children should never interact with each other online is not helpful in improving online safety for children, while educating people about what types of interactions are and aren’t appropriate is way better, and I would argue essential in online safety education.
Having adults with healthy relationships with is beneficial for children’s growth, because they would have trusted adults with more life experience than them that they can learn and get advice from, and it gives children a frame of reference for what healthy relationships with adults are like, and thus improving their ability to recognise if some other adults are being inappropriate to children.
