I can't tell you who should properly be credited with this insight, but it wasn't me.
The right-wing nutsos who got us into this war are all-fired up about saving the lives of fetuses and folks in a persistent vegetative state and, for that matter, embryos. They don't, however, seem to care so much about sending people to war to lose their lives in violent and tragic circumstances.
We are subjecting human beings to life-threatening conditions, knowing that a certain percentage of them are going to die. This is something those right-wingers would never let happen to an embryo, because it's too precious.
