There is no sentience present, and certainly no sapience.
A decapitated ant will kick, it does not say any useful about how aware the ant is.
That wasn't the argument. The argument was that there is no software present in the brain of the baby(which is ridiculous considering there's brain activity from, if memory serves, roughly the sixth week in onward).
Of course they do. A fetus begins exhibiting such things in sixth of seventh month of gestation. But yes, I would say a 5-month fetus has no software yet.
There's the capacity for emotion quite some time before that according to wiki. Also the above answer.
I consider your opinion ignorant of biology and immoral.
A clump of cells does not have rights because, well, it's a miniscule clump of cells, and if you consider abortion to be murder then you are denying women the right to do what they will with their bodies.
At what point, exactly, and with what change, exactly, does a clump of cells that you are uncomfortable calling human become a clump of cells that you feel comfortable calling human, considering that you, yourself, are a clump of cells?
I deny women the right to murder me, and will oppose any such attempt with utterly lethal force, is that immoral? I'm denying them the right to do what they want with their body, after all.
So is contraception manslaughter?
Not unless you're also positing masturbation being murder, any woman who doesn't have pop out a kid every nine months from when she begins menstruation being a murderer and so on and so forth.
Why does a potential person only come into existance at conception? The sperm and egg already exist, so they are potential people just like after fertailization.
And this would also mean that any form of contraception that does not prevent fertailization would also be murder.
The sperm and the egg may already exist, but they are not joined; the person isn't set[the DNA has not been finalised]; there are infinity billion other sperm that any one sperm has to beat to the egg. There is no person, yet. There's not even a potential person, yet. Hence, there is no potential for manslaughter.
