Help, do not shame
Answer the family in front of you. Disagreement is welcome; insults, harassment, and dogpiling are not.
Most people arrive here on a bad day — a child who will not talk, a phone they do not understand, a decision they already regret. Answer the question that was asked before you correct the person asking it. If you think their approach is wrong, say what you would do instead and why. What gets removed: name-calling, pile-ons, mockery of a parent or a teenager, and replies that exist only to score a point.
