God performs abortions all the time. I've known many would-be mothers who were traumatized by spontaneous loss of their pregnancies. There are times when for their own reasons women do not want to continue their pregnancies and I do not think the government should force them to continue them against their will. There are fetuses in the womb which may be identified as carrying major defects which would make their lives a burden for themselves and their families. Babies should be born healthy and wanted by their mothers and their fathers.
There are stupid reasons for terminating pregnancies, also (sex selection, for instance). The world and its systems are not perfect. I choose to err on the side of family choice.
