Unfortunately, those who back the extermination of innocent life, like to put it into such simple comparisons.
I'm going to snip the rest of your post which consisted of nothing but completely-unjustified (insofar as you don't know who I am in any way, sir) ad homs and personal insults, and deal just with this which at least vaguely resembles an argument.
It's a perfectly valid comparison, and apparently you missed the point of it. The point being that "extermination of life" (innocent or otherwise) is not what we need to be looking for. Not even if we add "human" in front of "life," which we should and which is why I used the shaving example and didn't go with, say, stepping on a cockroach.
When I cut myself shaving, I have destroyed "human life." If I punch someone in the nose and cause a nosebleed, I have destroyed "human life." Every month, every woman of childbearing age who is not pregnant destroys "human life," or at least her body does. Every time a man ejaculates, he destroys "human life" in all of the sperm cells of his ejaculate that do not find and fertilize an ovum.
Many cells are "human life" which are not
persons. And there is no question that an embryo at conception is "human life." The question is whether it is a
person. And I insist that it is not.
