There are plenty of loving families/couples who will adopt a baby and make them feel loved. I would know, I am friends with a couple of adopted kids.
Sure there are.
There also aren't nearly enough. Adoption centers are often, to say the least, unpleasant and the foster care system is lacking. The entire thing is all around underfunded and over populated.
Why should a woman have to spend 9 months carrying around what is basically a parasite and then give birth to it if she doesn't want to?
What gives you the right to say that you can take a life?
What it comes down to is this.
Mother's rights.
Unborn child's rights.
The mother is a fully developed human being with social connections and emotions. She is capable of thought and feeling pain, and has the right in society to make decisions for herself.
The unborn child is, at best, a possible future human. It is not developed enough to live outside the mother and is incapable of feeling pain or thinking. Up to 7 weeks, it doesn't even have brain activity.
It seems fairly obvious to me that, at minimum, a woman should be able to choose to have an abortion, at the very least, 7 weeks after conception.
