No, I'm not a parent.
Honestly, I find war itself to be pretty sick.
I find it sick to have anybody signing bombs, in that I find bombs themselves to be pretty sick.
I don't think you're wrong to find it sick to have children signing bombs, but I also don't think the Israelis are wrong to have their children signing bombs, if that's what they feel is necessary to raise their children properly in a place where bombs go off in their neighborhoods on a regular basis.
I think you're underestimating the difference between parenting children in America and parenting children in a place like Israel that has been a war zone for generations; even more than I'm underestimating the difference between not-parenting and parenting.
Edited to add:
I mean, Israeli parents don't have the luxury you have, TW, of teaching their children that war is a violent and horrible sickness, that only ever happens very far away, and that they can grow up in total ignorance of. That "very far away" to you is "right here at home" to them, and for the survival of their nation and their people, they can't really afford to let their children grow up in ignorance of it--if that were even possible.
