fetus's are alive too, just so you know. I know you might already know this, but it seems like you are ignoring that fact, so there goes that argument.
I'm saying that it is dumb to use cells designed purely for reproduction as an argument for abortion. It doesn't make sense to say something like "sperm is alive so let's not kill it!" because even though it is alive it, 1. Isn't a human but sperm, 2. can only swim and fertilize an egg.
