You may be reading too much into it. It assumes that we all get excited when we find out there's a bacterium on Mars, because life on Mars excites us, even if it's just a microbe.
Then they are saying why can't we be so excited about the life of an unborn child down here.
I realize it's apples and oranges, but the contrast does make you think. Because a lot of us DO take life for granted on this planet.
I'm still pro choice, by the way. But the way they put it made me look at it in a new light is all.
is the issue "life" or "human life?" because we kill the shiat out of almost everything on our own planet without giving it a second thought.
