What's with Delta Green and kids?

When discussing what players are comfortable and not comfortable with before starting play, even my strongest-stomached players tend to say "not a fan of anything involving bad stuff happening to kids."

Yet playing DG scenarios, it's almost impossible to avoid. We all know about God's Teeth, but you also have >!Operation Fulminate, Ex Oblivione, Extremophilia, arguably/potentially Convergence, Puppet Shows and Shadow Plays, and Impossible Landscapes!<, just to name 6 of who knows how many, all contain Bad Things Done To Kids.

What gives?

I suppose it is particularly *horrific*, but why is it that DG writers return to this so often? Edit: Couple more classic examples - >!Sweetness, kinda Victim of the Art but not exactly (they're older I guess), From The Dust which actually inspired this post as I'm running it tomorrow!<

Edit 2: Just to be clear, this is not a complaint, it's just something I've noticed
