"Prepare to Give Birth"

Can the religious fanatics stop their obsession with fetuses already?

Some people tell you that they are against abortion because they are against destroying a life (Forget about the right of the woman to decide; her sole job is to breed anyway).
But I'm really wondering; when exactly is it considered a life? The moment the sperm fertilizes the egg cell? Why not even before?

I think that the sperm itself is a life and shouldn't be destroyed: Guys, no more masturbation!
