Why is this attached to my comment? My comment has nothing whatsoever to do with abortion. (Which I not only do not want to ban, at the very least I'd like it to go back to how it was under Roe v Wade).
My comment was about people misusing the terms life and alive. The correct way to argue that abortion should be legal is not to redefine life and/or alive so that some living cells or collections of living cells do not qualify rather than trying to redefine common terms used by biologists.
The correct way is to argue that we only only protect some cells or collections of cells and not others and then to argue that fetal cells belong in the not protected group. The question then comes down to deciding what it is that makes some groups of living cells protected but not others. Probably the best argument would be something along the lines that before that collection of cells has grown and developed to the point that it has a brain that can think and feel it is not really different from a tumor or other collection of cells that we don't protect.
