Again. I have never said that unborns were either emotional or intelligent. Neither of those are requirements of being human beings.
If you are arguing for the rights of animals, then start a thread. This one is not about animal rights.
Well then what makes a human really special when it is in the womb compared to an animal? Especially if it is, for example, going to be so severely disabled that it cannot truely think, or posess emotions and real intelligence. Simply that it is human? Because it looks like us? In that case its just as justified for people to say "whites are better than blacks, because they look like me."
I'm using the idea of specism to highlight the fact that a human embyro is less intelligent than other animals you have less desire to keep alive, and you simply favour it because it is of the same species as you, not because of what it is in the womb. In the womb, a child is nothing, it is potential, and potential that should be allowed to happen, but it is still not an intelligent, thinking being worthy of a decision. It doesn't know its living, so it wont know when its not living.
