Got it: you believe it's acceptable to slaughter children for any reason (or no reason) provided they're young enough, but instead of "championing" it maybe you feel a little bit bad when it happens.
So if I understand correctly, the primary moral innovation modernity has discovered with regard to child slaughter is "we still do it, but now some of us feel a little bit bad about doing it while still defending the practice".
If I had a point other than simple mockery it would be "people in glass houses shouldn't throw stones".
