When a parent kills an autistic child, it's so predictable. People come out of the woodwork to defend the killer, demand we walk in her shoes, to stomp their feet and demand of me "how dare you judge?"
How dare you not?
Who are you to decide that a child's life is so not worth living that killing them is a good thing? How dare you cheer on abuse and murder? How dare you support execution of someone for the crime of having a disability? How do you live with yourself?
Judging someone for rocketing past the fuzzy zone and straight into "that is just awful" territory is easy. It should be reflex, easy as a blink or a sneeze. Our (well, my. USian) culture has a big taboo, though, against this evolutionarily advantageous reflex, and it blames the Bible.
Here's the thing though. That "judge not lest ye be judged" thing that people like to throw out? It doesn't say "do not evaluate things". It doesn't say "thou shalt not come to conclusions and announce them". It says "you will be held to the same standards you hold others to".
"Don't kill your kid" is a pretty low standard. I have no doubt in my mind that I can life the rest of my days without committing, or even considering, infanticide. I'm a bit terrified, though, of all the parents who feel this is too stringent a standard, who are eager to make clear that maybe they will kill their kid, they're just not sure that "no killing" is a fair expectation.
In a world where "not murdering your child" is a standard many people are unwilling to commit to live by, a world where unrepentant murderers have cheering squads, no young or dependent person is safe. I fear for the children of people screaming "don't judge". When you shout at, harass, threaten me for holding folks to this very minimals standards, you are saying you don't think you can meet it (or can't be assed to try, speaking of scary). This doesn't make me the problematic person in the scenario.
"Don't kill people" is a standard that should be effortless. People who can't or won't meet it should be judged, swiftly and harshly. It should be as easy as a blink. It is as easy as a blink. If you can't be sure you can meet this standard, that's your deficit. I will continue to easily, effortlessly judge people who kill their children and dependents, because evaluating "that is not an acceptable action" is the right thing to do.
