I can not like this enough, excellently put! We might not say direct mean things about the family on here, but people do use passive aggressiveness to imply the same with vague sarcasm or winking emojis, it may not be the same vicious direct comments, but I think we all know what those type of comments are implying and I think if the family read some of them they would know what they're implying too because it's easy to read between the lines and although not as direct and vicious, if they are innocent and saw them, they will still have a hurtful and harmful effect. Those boys are innocent children, regardless of what their parents or parent may or may not have done and one day they may come across comments online, they have enough to deal with already and lets be honest, the future, however things go, will be incredibly difficult too. I'm a psychotherapist and I can tell you, even if a parent is guilty, their remaining children will still love their parent to some degree and even indirect comments with obvious not so nice undertones will hurt.
My heart hurts so much for those boys, they must be so confused by the response, their world has been turned upside down and their emotional stability shaken to the core, I hope to god they are receiving and will continue to receive professional emotional support, as well as their parents if not guilty, but most of all I hope to god Summer is found and if she's not in this world anymore, I hope the mystery of what happened to her is solved and any guilty parties are held accountable.
