In all human enterprise, people kill other people for convenience, and claim just purpose, or present the "unavoidable" excuse, or just turn a blind eye to another's fatal circumstance. We generally do not talk candidly about the whole realm of who gets to live and fulfill their potential and who gets to die for want of sufficient nurture from fellow humans.
It seems bogus to me for one to focus on this area of human activity to draw a line. How about the overt acts of war we humans regularly justify? How about the routine denial of our surplus substance to hundreds of millions around the world, while watching them starve to death? How about the squalor that some children is this very country suffer?
Unless pro-lifer's live like Mother Teresa, I believe their agenda is more of a control issue. And I am anti-abortion! But it is quite clear to me that many will die in furtherance of my convenience.
There will always be death, murder and mayhem. There will be wars, acts of terror and hunger and death from disease and mutilation by rabid dictators. But there does NOT have to be the crushing of life, the ripping of a growing infant from the womb. To compare the denial of a long life to a newly growing infant to war and pestilance and hunger and murder is ridiculous. All it takes to kill an infant is a sick woman, a equally sick partner in some instances and a very sick doctor. Oh, a great big bunch of denial and lack of conscience.
