When the chances of a successful pregnancy are 9/10 at the highest, or 75% at the lowest, I'd say that is still a pretty large chance of the fetus turning into a human,
It's a high-ish chance, yes. It's not certain though by any means that, once pregnant, that fetus will be born eventually. Especially if you take into account stupid arguments like "condoms can fail!" in contraception debates, and their lowest number is higher than that.
where the differences are to large, and the similarities to small?
In the terms of the point I was making, the differences were minute. Yes, a building isn't living. Yes, a fetus isn't composed of distinct separate parts. That's not the point of the analogy.
I'll rephrase this and ask my question again: "do you think it would be RIGHT to kill a veggie who is brain dead because no one likes him or her and they're a small nuisance (on the grand scale of things) to society?
No, not for those reasons alone.
Ah, so you consider a human skeleton a human and a person?
No, I consider it to be something which -was- a -part- of a human.
You would walk up to a human skeleton and say "what's up?"
I wouldn't, but what do you call visits to the grave?
You consider anything that was a human and developed a connection with people humans?
Did I ever say this? No, so please, stop trying to put words in my mouth.
you should consider a fetus a person.
I consider it a possible person to be. This isn't the same as saying it's not a person at all, or has no rights.
I don't think that to be a person you must have had, had connections or relationships with other humans.
I don't think that either. This is just one difference between a fully developed person and a fetus.
For the sake of clarity...
I do not advocate abortion as something to be considered easily, nor do I advocate it on any one reason. My reasons for saying that it should be legal are numerous, some of which alone would not be sufficient.
