I truly feel for those who lost a child, as does most everyone else. But lets call it what it really is, show boating. They trot out these grieving parents, knowing full well what most of them will say. And those who do not say what they want them to say, we hear little about.
The question the father posed was for the most part, rhetorical, he expected no answer. After all he is a grieving father, we are to feel sorry for him. Even though he expected no one to answer his question was for that reason, he show boated by looking around as if to challenge/dare anyone to answer. It would be shameful to attack a grieving father and anyone who said anything other than agreement should and would be shamed.
They know respectful people, well have a hard time challenging an obviously grieving person. As show by the amount of time that pasted and the looking around by the father in his dare/challenge, before someone said something.
It is not shameful to make a reasonable statement, to a person who has said something foolish, no matter how much they may be grieving. In fact no matter how wrong it may seem, injecting reason into the conversation may be the best thing to do, rather than allow them to continue their delusion.
The father suffered a horrible, terrible loss. To which there are no real answers, as to why it happened. And in my view trotting him out as they have done in his time of grief and sorrow and using that to further their agenda, is more Shameful by a long shot than the person or persons who answered his question, Challenge/dare, with a logical and reasonable answer. And such challenges should not be allowed to go unanswered. JMHO.
