Well, I guess you could point out that there are actual dead children, whose actual dead bodies were carried out of the school by actual people, and then examined by an actual medical examiner, and then interred by an actual funeral director, and buried in an actual grave, while these "lying liars who lie" stood by.
I'm sure that each of the liars who lost a child WISH they were lying about their children being dead.
On the other hand, most of us aren't obsessing over the grief patterns of the parents of 6-year-olds horribly killed in a senseless act of violence. SO long as they aren't trying to take rights away, I don't even CARE if they aren't perfectly truthful when they speak of their relationship with their kids, or their feelings.
The only purpose to bring up this kind or ridiculous argument is to try to assert that there were not actual dead kids. Once you are forced to accept the basic, undeniable FACT of dead children, it really makes NO DIFFERENCE at all whether Crazy Gene is looking for a moment of fame, or some parent or another can't cry on demand, or has a rose-colored view of their life that wouldn't stand up to scrutiny.
But sadly, some people seem to think that is all that matters.
