Of course adoption is an option, but most people do not even think of doing this and have an abortion instead.
If there was no abortion there would be one less option. Raise the child yourself, give it up for adoption. As it stands now there is a third, abortion.
This is what I mean by naive. The entire question is absurd since most abortions, well over 99% are NOT from rape or incest. It is the pro-aborts biggest canard and should be treated as such.
